"The first rule in investment is don't lose and the second rule in investment is don't forget the first rule." - Warren Buffett

---

Builder's risk insurance protects a property, and the materials going into it, while the property is being renovated or built. For an Oklahoma investor working on a single-family house, a duplex or a fourplex, that is the riskiest stretch of the deal. The house is usually empty. Walls, roofs and plumbing are open. Copper, cabinets and appliances sit on site. And in Oklahoma the house may sit open through the heart of tornado season, when one supercell can drop a tornado or a hailstorm that turns a routine rehab into a total loss.

This guide covers builder's risk for Oklahoma investors working on 1 to 4 unit properties: house flips, BRRRR rehabs, value-add work on 2 to 4 unit, and ground-up or infill builds. It shows which policy fits which project, what is covered and what is not, how percentage wind and hail deductibles and the state's induced earthquakes change the math, what your lender requires, and how to keep a claim from being cut or denied.

Key Takeaways

• Builder's risk is temporary property coverage for the rehab or build. It does not include liability, so most investors are better served by a fix and flip policy that bundles property, vacancy and liability coverage.
• Tornadoes and hail are the losses that define an Oklahoma rehab. The state sits in the heart of Tornado Alley, and a house with an open roof is the most exposed building on the block.
• Expect a separate wind and hail deductible, set as a percentage of the dwelling limit, so a storm claim costs far more out of pocket than a fire or theft claim.
• Do not accept a wind or hail exclusion on a financed deal. Lenders require the coverage, and it is the most likely major Oklahoma loss.
• Earthquakes are a real Oklahoma exposure, driven by wastewater injection from oil and gas activity. Standard property and builder's risk policies exclude earth movement, so earthquake is a separate decision.
• Flood is excluded and needs a separate policy. Oklahoma sees damaging flash floods well beyond the mapped coastline.
• Price ordinance or law coverage on older homes. Repeated hail and wind events make roof and code upgrade costs a real exposure.
• Insure to the right value. Underinsuring reduces every claim payment, not only total losses, and a limit raised without your approval costs you premium for nothing.

Which Policy Fits Your Project

The most common insurance mistake we see on an Oklahoma rehab is buying the wrong kind of policy for the work. Three questions decide the answer: how big is the scope, does anyone live in the building, and are you renovating or building new?

---

---

Light cosmetic rehab on a vacant house. Paint, flooring, fixtures and similar work can fit a vacant dwelling policy that allows renovation, or a fix and flip policy with a vacancy endorsement. Watch two things. Vacant dwelling programs often cap the size of the renovation they will accept as a percentage of the property's value, and some leave wind and hail out as standard. A missing wind peril conflicts with lender requirements.

Substantial or structural rehab. Roof replacement, new systems, moved walls and additions call for coverage built for construction risk. Carriers rate structural work higher than cosmetic work because the existing house is more exposed while walls, roofs and floors are open. Describe the scope accurately on the application, because a cosmetic policy on a structural job is a claim dispute waiting to happen.

Storm-damaged property bought as is. Many Oklahoma listings are hail or wind damaged. These need a policy that will accept existing, unrepaired damage, with the understanding that damage present before the policy started is not covered. Document the condition at purchase with dated photos.

Gut rehab. A full gut is still a renovation, not new construction, because a structure existed when the project began. That matters because the existing house needs to be insured, not only the new work.

Rehab with tenants in some units. On a duplex, triplex or fourplex, renovation coverage often allows some occupancy but ends once leasing passes a set share of the units, commonly half. A fix and flip policy may not cover active tenants at all, in which case you need a landlord policy or a hybrid policy that accommodates occupancy.

Ground-up or infill build. New one to four family homes fit builder's risk new construction coverage, written on completed value from the day materials arrive, and built to the current Oklahoma building code. Add general liability separately.

The finished rental. Once the property is rehabbed and rented, you no longer need builder's risk. A landlord policy on a dwelling fire special form (DP-3) is the standard fit. Lenders that accept dwelling fire forms typically require the special form.

Tornado, Hail and Wind Coverage in Oklahoma

This is the coverage that defines an Oklahoma rehab, and the one most often limited by an exclusion or a separate deductible.

---

---

Oklahoma Sits in the Heart of Tornado Alley

Oklahoma is one of the most tornado-prone places on earth, and the Oklahoma City metro is the most striking example. Moore alone has been hit by violent tornadoes again and again: an F5 on May 3, 1999 that killed 36 people and caused about $1 billion in damage, an F4 in 2003, an EF4 in 2010, and an EF5 on May 20, 2013 that killed 24 people, damaged an estimated 1,200 homes, destroyed two schools and caused more than $2 billion in damage.

Tornado season peaks in spring. Across the country, 54 percent of tornadoes occur between April and June, and May is the most active month of all. The typical flip took about 161 days from purchase to resale in the second quarter of 2026 (ATTOM), so an Oklahoma rehab that starts in late winter will spend the peak of the season under construction, often with an open roof.

Hail Is the More Frequent Claim

Tornadoes make the news, but hail is the loss Oklahoma investors file most often. The same supercells that spawn tornadoes drop large hail across Oklahoma City, Tulsa and the whole central corridor most springs, and a single storm can total the roofs across an entire neighborhood. On a rehab, a hailstorm that hits before the new roof is on, or just after, is a direct and expensive loss.

How Oklahoma Wind and Hail Deductibles Work

Most Oklahoma property policies now carry a separate wind and hail deductible, set as a percentage of the dwelling limit rather than a flat dollar amount. Flat wind and hail deductibles have become the exception in the state.

• The deductible is calculated on the dwelling (Coverage A) limit, not on the size of the loss. Common levels are 1 percent, 2 percent as a standard, and 5 percent in higher-risk situations.
• On a $350,000 dwelling limit, a 2 percent wind and hail deductible is $7,000, and a 5 percent deductible is $17,500. You pay that amount before the policy pays anything on a wind or hail claim.
• The all other perils deductible, which applies to fire, theft and water, is usually a separate, smaller flat amount. A single policy can carry both.

Find the wind and hail deductible on the declarations page of your actual quote and write it into your budget, because it is the number that decides what a storm claim really costs you.

Size Your Reserves to the Wind Deductible

Because the deductible is a percentage of the insured value, a higher limit means a higher out-of-pocket number on every storm. That is why an Oklahoma rehab budget needs a reserve line for wind and hail, separate from the general contingency, and why our team pushes back on an uncapped percentage deductible.

Do Not Accept a Wind or Hail Exclusion on a Financed Deal

Some vacant and renovation policies leave wind and hail out as a standard feature, or offer the peril only as an option. On a financed Oklahoma deal that will not satisfy your lender. Our lending guidelines do not allow windstorm, hail or named storm exclusions, so read the covered perils as well as the premium.

Secure the Site When Storms Threaten

A house under renovation is a job site, and loose materials become windborne debris that can damage your house and the houses next door, which brings your general liability into the loss. During the spring storm season, keep the roof dried in where the schedule allows, tie down or remove loose materials, secure the dumpster and portable toilet, and move uninstalled materials into a locked, enclosed space. Put storm preparation in your contractor agreement.

Earthquakes and Induced Seismicity

Oklahoma is the one inland rehab market where earthquake belongs on the checklist, because much of the state's shaking is man-made.

---

---

Why Oklahoma Shakes

Oklahoma went from a couple of magnitude 3.0 or larger earthquakes a year in 2008 to 109 in 2013 and 907 in 2015, a surge the Oklahoma Geological Survey links to the injection of wastewater from oil and gas activity into underground disposal wells. The largest on record struck near Pawnee on September 3, 2016 at magnitude 5.8, slightly larger than the 2011 Prague quake. Regulators have since curbed injection and the frequency has come down, but the exposure has not gone to zero.

How Earthquake Coverage Works

Earthquake is treated as earth movement, which standard property policies and builder's risk and fix and flip policies exclude. Covering it means a separate earthquake policy or endorsement. A few points matter for investors:

• Coverage grew fast, then leveled off. About 15 percent of Oklahomans carried earthquake coverage after the swarm, up from about 2 percent in 2011, with premiums commonly running $50 to $300 a year.

• The deductible is a percentage, and it applies per event. Earthquake deductibles are a share of the insured value rather than a flat figure. Because they apply per quake, a series of smaller tremors can leave you absorbing most of the damage.

• Induced quakes are a policy-language question. Whether a policy responds to an oil and gas-induced quake depends on its wording. If earthquake matters on your deal, ask the carrier in writing whether induced seismicity is covered.

  For most 1 to 4 unit flips, earthquake remains an optional decision rather than a lender requirement, but on a masonry or unreinforced older house in central Oklahoma it is worth pricing.

Flood in Oklahoma

---

---

Flood Needs a Separate Policy

Builder's risk and fix and flip policies exclude flood, so a property in a FEMA special flood hazard area needs a separate flood policy, and lenders require one.

Our guidelines set the flood limit at the greater of $250,000 or the loan balance. NFIP flood policies normally have a 30-day waiting period, but FEMA waives it when the policy is purchased in connection with making, increasing, extending or renewing a loan. Buy the flood policy at loan closing.

Flash Flooding Reaches Beyond the Map

The same spring storms that bring tornadoes and hail also bring heavy, fast rain, and Oklahoma sees damaging flash floods in low-lying parts of Oklahoma City, Tulsa and river communities that are not always inside a mapped flood zone. A cash buyer with no lender mandate should still price flood on a property with any history of water, and a rental you plan to hold in a special flood hazard area still needs flood insurance under DSCR loan guidelines. Our comparison of landlord and flood insurance explains how the two work together.

Oklahoma Roofs, Building Code and Ordinance or Law

---

---

The Roof Is the Center of an Oklahoma Rehab

In a state hit by hail and wind every spring, the roof is the single most important part of the building for insurance. A new, properly installed roof is the strongest thing you can do for both insurability and claim outcomes, and it is also the part of the house a storm is most likely to take. Price the roof carefully, keep the product documentation, and get it dried in before the storm season where the schedule allows.

Roofers Must Be Registered

Oklahoma requires roofing contractors to be registered with the Construction Industries Board. Residential roofing registration requires proof of general liability insurance and workers' compensation, and commercial roofing requires an exam and a separate endorsement (House Call Pro). Confirm your roofer holds the current registration and carries real general liability before the crew gets on your roof, because an uninsured fall on your project can land on you.

Why Ordinance or Law Coverage Matters

Ordinance or law coverage pays for costs that come from enforcing current building codes after a covered loss. It usually has three parts: the value of the undamaged portion that code forces you to tear down, the cost to demolish it, and the added cost to rebuild to current code. Many policies default to 10 percent of the building limit. On fix and flip quotes our team typically requests 25 percent, and older Oklahoma housing stock is where it pays off most. When a roof or a wall is rebuilt after a storm, current code can require upgrades the old structure never had.

Surplus Lines, Taxes and Carrier Strength in Oklahoma

Many Oklahoma fix and flip and vacant home policies come from surplus lines carriers. These are insurers not licensed in Oklahoma the same way as standard home insurers, but allowed to cover homes that standard carriers turn down, which is often the case for a vacant house under renovation. Two points belong on every quote review.

The tax. Oklahoma charges a surplus lines premium tax of 6 percent of gross premium, which includes premium and fees, plus a small transaction fee on the broker's filing. Compare quotes on total cost, not base premium.

No guaranty fund. If a standard Oklahoma-licensed insurer fails, the state guaranty association steps in to pay covered claims within limits. Surplus lines policyholders do not have that protection, and Oklahoma requires surplus lines policies to carry a bold-face notice that they are not subject to any guaranty association. That makes carrier financial strength more important, and it is one reason lenders require an AM Best rating of A- VIII or better. Our guide to AM Best ratings explains what the rating means.

How Much Builder's Risk Insurance Costs in Oklahoma

The honest answer is that location and construction drive almost everything, and in Oklahoma the wind and hail exposure sits over all of it. Here is the range OfferMarket investors typically see on 1 to 4 unit Oklahoma deals, by property value and rehab budget:

---

---

These ranges cover the property and renovation coverage. A property in a high-hail corridor, or one with an older roof, prices toward the top of the range, and the percentage wind and hail deductible climbs with the limit.

For context, builder's risk nationally runs about 1 to 4 percent of completed value, and standalone policies carry a minimum premium floor regardless of project size. Because Oklahoma pricing swings with location, construction and roof age, the only reliable number is a quote on your property. For bundled rehab coverage, see our fix and flip insurance guide.

Refunds When the Project Ends Early

OfferMarket fix and flip premiums are generally refunded pro rata when you cancel early, most often after a sale or after refinancing into a DSCR loan and switching to landlord insurance. Not every builder's risk policy works that way. Some new construction policies are fully earned, which means no refund for unused time. Ask before you bind.

What Factors Influence Builder's Risk Insurance Cost?

Builder's risk is priced on the risk the carrier takes on during the project, and that risk shifts with the property, the work and the policy itself.

---

---

1. Location

Where the property sits is the single biggest driver of cost, and in Oklahoma it dominates. Carriers look at:

• Exposure to tornadoes, hail and straight-line winds
• Flood zone and flash-flood exposure
• Earthquake exposure in the central part of the state
• Distance to a fire station and the local fire protection class
• Crime and vandalism rates on the block

You cannot move the house, but you can make sure the quote is built on the right address, protection class and flood zone determination. An error in any of these inflates the premium.

2. Project Type

Carriers rate new construction, installation and remodeling differently, based on how much the existing structure adds to the risk.

• New construction and simple installations usually cost the least, because the timeline is short and there is no existing building to protect.
• Remodeling is rated highest, because an existing structure is exposed to loss the entire time the work is underway.
• A cosmetic remodel rates lower than a structural remodel that moves load-bearing walls, changes the foundation or adds a story.

Describe the scope accurately to the agent. Understating it to shave premium is the fastest way to have a large claim disputed.

3. Construction Type

The materials the house is built from decide how well it survives a fire or storm.

• Masonry and fire-resistive construction rate most favorably.
• Wood frame rates least favorably, and most Oklahoma housing stock is wood frame.

4. Optional Coverages

The base policy covers the core perils. Every endorsement adds premium, so match them to the project. On an Oklahoma rehab the options worth discussing are:

• Flood, which is excluded as standard
• Earthquake, where the risk exists
• Soft costs: extra loan interest, taxes and fees during a covered delay
• Loss of rents, for units with tenants
• Materials in transit and in temporary off-site storage
• Increased cost from change orders, when the scope is likely to grow
• Sewer, drain or sump backup

5. Additional Fees and Taxes

Two policies with similar base premiums can cost very different amounts once fees and taxes are added, and that comes down to the type of carrier.

• Admitted carriers are licensed in Oklahoma and backed by the state guaranty association if the insurer fails.
• Non-admitted (surplus lines) carriers write many vacant and renovation policies that admitted carriers decline. They add the 6 percent surplus lines tax and can add policy fees, and they are not backed by the guaranty fund.

Compare quotes on total cost, not the base premium, and require an AM Best rating of A- VIII or better.

Three More Factors We Weigh for Investors

• Vacancy and timeline. A house that has sat empty for years, or a project expected to run past 12 months, carries more risk and often more premium. A realistic timeline prevents costly mid-project extensions and keeps you from sitting open through tornado season.

• The limit. Set it on completed value, without land and without padding. This is where we most often find overpayment, and occasionally a dangerous shortfall that triggers a coinsurance penalty at claim time.

• The deductible. A higher deductible lowers premium, but lenders cap it. Our guidelines cap the property deductible at the lesser of 5 percent or $5,000, so we push back on an uncapped percentage wind and hail deductible that would run above that, such as a straight 5 percent on a high limit.

How to Lower Your Builder's Risk Cost Without Creating a Gap

You can bring the premium down without leaving a hole in the coverage:

• Insure to an accurate completed value, without padding

• Choose the highest deductible your lender accepts and your reserves can absorb, within the 5 percent or $5,000 cap

• Replace an old roof early in the project, which helps both insurability and claim outcomes

• Secure the site with locks, lighting and cameras

• Keep the schedule realistic, so you avoid extension charges and stay ahead of the spring storm season

• Compare quotes line by line, not only on price

  Never save money by dropping vacancy, wind and hail, liability or theft protection. Those gaps turn ordinary Oklahoma losses into uninsured ones.

What Our Quality Control Catches on Outside Quotes

Every quote that comes through OfferMarket is checked by our QC team against the investor's request and the lender's guidelines before it is bound. These are the problems we flag most often, and the reason we tell investors never to judge a quote by the premium alone.

The wrong policy type for the project. A landlord policy quoted on a vacant gut rehab, or a vacant renovation program quoted on a property the investor plans to rent right away.

An uncapped percentage wind and hail deductible. A straight 5 percent wind and hail deductible on a $300,000 limit puts the first $15,000 of a storm claim on you. Our guideline caps the deductible at the lesser of 5 percent or $5,000, so we ask for a flat $5,000 or a percentage capped so it cannot exceed $5,000. This is the Oklahoma catch that costs investors the most.

A wind or hail exclusion. Some vacant and renovation forms leave the state's most likely major loss uninsured. We do not allow it on a financed deal.

A dwelling limit the investor did not ask for. Agents sometimes raise or lower the limit without approval. Raising it adds premium for coverage you could never collect. Lowering it can trigger a coinsurance penalty on every claim.

Functional replacement cost in place of replacement cost. The two look similar on a summary page, but functional replacement cost can pay noticeably less on an older house.

Land value deducted from the coverage. Some renovation forms limit what they will pay to the investor's actual capital in the project, minus land value. We ask for it to be removed or explained in writing.

Thin ordinance or law coverage. Many quotes default to 10 percent. On fix and flip policies, we request 25 percent, which matters more in Oklahoma because of the roof and code exposure.

Missing water backup. Sewer and drain backup is a common claim and is often left off unless requested.

Liability below lender limits. Fix and flip policies need $1,000,000 per occurrence and $2,000,000 aggregate. Landlord policies on our DSCR loans need $500,000 per occurrence.

Mortgagee and additional insured confused. The lender needs to be the mortgagee on the property coverage and an additional insured on the liability coverage.

No vacancy endorsement. The most expensive omission of all.

Cases From Our Quality Control Desk

These are real situations our team handled, anonymized and summarized.

The deductible that changed the math. On a property in a high-hail corridor, a quote came back with a wind and hail deductible set at 5 percent of the total insured value instead of a flat dollar amount. On a storm-exposed home, that one line can be worth more than a year of premium savings. We asked for a capped deductible and showed the investor both versions side by side. The lesson: compare deductibles in dollars, not percentages.

A renovation form on a rental request. An investor asked for landlord coverage on a property ready to rent. The quote came back on a vacant and renovation program built for fix and flip projects, with fix and flip liability limits, a flat loss of rent figure that did not match a 12-month standard, and no confirmation of water backup. We asked for a requote on landlord terms and written confirmation of the policy form. The lesson: the policy type has to match what will happen at the property, not what is easiest to quote.

The limit that grew without approval. An investor asked for a dwelling limit that matched the rebuild cost. The quote came back far higher, because the carrier had raised it to satisfy its own replacement cost estimate, which meant more premium than the investor had planned for. We pushed back, asked the agent to justify the figure and requested pricing on the endorsements the quote left out, including water backup and ordinance or law. The lesson: compare the quoted limit to the one you requested before you look at the price.

What Your Lender Requires

The property is your lender's collateral, so the lender's insurance guidelines shape the policy as much as your own preferences do. This table compares typical requirements during the rehab with the requirements after a refinance into a DSCR loan.

---

---

---

The mortgagee clause. List the lender's exact name and address followed by ISAOA/ATIMA. OfferMarket's clause reads OfferMarket Capital LLC ISAOA/ATIMA, 627 S Hanover St, Baltimore, MD 21230. More detail is in our mortgagee clause glossary entry.

Proof of insurance. OfferMarket requires an ACORD form, plus certificates and paid receipts, at least 24 hours before closing, and final policy documents within 60 days after closing.

Carrier strength. An AM Best rating of A- falls in the Excellent category, and Financial Size Category VIII means policyholder surplus of $100 million to $250 million. This matters more in Oklahoma, where many renovation policies are written in the surplus lines market with no guaranty fund backstop.

Why Financing and Insurance in One Place Matters

Most closing delays caused by insurance come down to a mismatch between the policy and the loan: a wind or hail exclusion, a deductible the lender will not accept, a liability limit too low, a flood policy bound too late or a mortgagee clause with the wrong name. When you use OfferMarket Capital for the loan and OfferMarket for the coverage, the same team that sets the loan requirements checks the policy against them before closing, not the day before.

What Builder's Risk Covers on a 1 to 4 Unit Project

Coverage depends on the policy form, so treat this section as a list of things to confirm rather than a promise of what any one policy includes.

---

---

The House and the Work

On a renovation, two values are at risk: the house you bought and the work you are adding. Not every builder's risk policy insures both.

For an investor, the loss that matters most is a tornado, hail or fire that takes the whole house, not only the new kitchen. Confirm in writing that the existing structure is insured from the day you close.

Materials on Site, in Storage and in Transit

Building materials are often the easiest thing to lose. OfferMarket's renovation coverage insures the structure, materials and equipment on the premises or within 100 feet, and the foundation.

If materials will be stored off site, ask for coverage at that location by name. A pallet of shingles or a staged HVAC unit sitting at another address is outside a site-only policy.

The Causes of Loss

Residential builder's risk commonly covers fire and lightning, wind and hail (when included), theft, vandalism, arson and collapse. Many policies add extensions such as debris removal, materials in transit, sewer or drain backup and ordinance or law, each with its own smaller limit. Ask for the sublimit on each one, especially debris removal, which is expensive after a tornado.

Theft: The Claim Investors Misunderstand Most

Theft is one of the most frequent construction claims, and residential job sites have predictable targets: copper wiring and pipe, appliances, HVAC condensers and fixtures.

Some policies exclude theft of building materials that are not yet attached to the structure, which means the new range or the condenser sitting in the garage may not be covered until installed. Before materials arrive, ask three questions:

• Is theft of uninstalled materials and appliances covered on site, in storage and in transit?
• Is there a sublimit?
• What security conditions apply? Then schedule deliveries as close to installation as your contractor allows.

Ordinance or Law for Older Homes

When a damaged older home is rebuilt, code can require upgrades to undamaged parts of the house. Ordinance or law coverage pays for the value of the undamaged portion code forces you to tear down, the cost to demolish it, and the increased cost to rebuild to code. On fix and flip quotes, our standard is 25% of the building limit. Many policies default to 10 percent, which can fall short on an older Oklahoma home.

What Builder's Risk Does Not Cover

---

---

Flood and flash flooding. Both are excluded. Rising water, including flash flooding from a spring storm, is a flood claim, not a wind claim, and needs a separate policy.

Earth movement and earthquakes. Builder's risk programs exclude earth movement, which includes Oklahoma's induced earthquakes. Covering it means a separate policy or endorsement, as explained above.

Pre-existing damage. A hail or wind-damaged house bought as is will not be covered for damage that existed before the policy started. Dated photos at closing protect you.

Faulty workmanship and defective materials. Builder's risk is not a warranty. Policies generally exclude the cost to correct faulty work, though a policy with an ensuing loss provision may cover resulting damage to other property.

Wear and tear, rot, pests and mold. Old plumbing, termite damage and gradual deterioration are maintenance problems. Mold coverage is often excluded or capped.

Frozen pipes in a vacant, unheated house. Oklahoma winters bring hard freezes and ice storms. On a vacant building, the resulting water damage is commonly covered only if you kept heat on or shut off and drained the water system. Leave a vacant house cold with water in the lines and a freeze loss can be denied.

Employee theft and worker injuries. Theft by the crew and injuries to workers are excluded. Workers belong under the contractor's workers' compensation.

Liability. A standalone builder's risk policy does not cover injuries to other people. The liability section below explains how to fill this gap.

Land and landscaping. Land, trees, shrubs and walkways are generally not covered, and land value should never be part of your limit.

One more gap is a belief rather than an exclusion. Some investors assume a general liability policy will cover damage to the project itself. It will not. Liability insurance covers what you owe other people. Builder's risk covers the project. A rehab needs both.

Vacancy: The Empty-House Problem

Most flips start with a vacant house, and standard policies often exclude or void coverage on unoccupied homes. More investor claims go wrong here than anywhere else.

---

---

How Vacancy Clauses Work on Residential Policies

In the standard homeowners form, coverage for glass breakage and vandalism ends once the dwelling has been vacant for more than 60 consecutive days. Dwelling policies work much the same way, and some older forms use 30 days.

Why "Under Renovation" May Not Protect You

Many policies say a home under construction is not considered vacant, but renovation can be treated differently. Gutting a home, with the contents removed and the occupants gone, can make it vacant, and visiting to check on progress does not change that.

Merlin Law Group states courts look for substantial, continuous construction activity, measured by how many workers were on the project and how much time they spent in the building. Even builder's risk can tighten when work stops, limiting coverage to named perils after a set period with no activity.

How Rehabs Drift Into Vacancy

The trap is rarely a decision to abandon a project. It is ordinary dead time: waiting on permits, a draw, a missing contractor or a buyer. A tornado or hailstorm that halts work for weeks can push a house past a vacancy threshold while no one watches the calendar.

The Fix

Disclose vacancy when you apply, and make sure the policy carries a vacant property endorsement or vacancy permit for the whole rehab period. Our lending guidelines require borrowers to notify the carrier when a property becomes vacant or unoccupied and to obtain a vacancy permit for the entire vacancy period. Back the endorsement with records: a dated work log, contractor invoices, inspection reports and weekly photos.

Liability on a Rehab

A builder's risk policy does not cover workplace injuries or liability. On an investor rehab, the liability exposure often outweighs the property exposure, which is why we pair renovation coverage with general liability on every fix and flip quote.

---

---

• Who can get hurt. Contractors and their crews, inspectors, appraisers, buyers' agents, neighbors and trespassers.

• Roofing crews and work at height. Hail and wind make roofing the most common Oklahoma trade, and a fall from a roof is a serious liability exposure. Confirm your roofer is registered and carries general liability and workers' compensation.

• Children and open job sites. Under the attractive nuisance doctrine, landowners may owe trespassing children a heightened duty when a dangerous condition is likely to attract them (Cornell Legal Information Institute). Open foundations and unsecured stairs are exactly that kind of condition. Fence and lock the site.

• What lenders require. Fix and flip lenders commonly require general liability of $1,000,000 per occurrence and $2,000,000 aggregate on an occurrence basis, with the lender as additional insured.

• Your contractors' coverage. Collect certificates of general liability and workers' compensation before work begins, and ask your contractor to add you as an additional insured by endorsement. If a contractor carries no coverage, the owner can become the target.

Contractor Licensing in Oklahoma

---

---

Oklahoma does not require a state general contractor license for general building work, but it does license specific trades through the Construction Industries Board, and cities add their own registration (House Call Pro).

• Trade licenses. The Construction Industries Board licenses plumbing, electrical, mechanical (HVAC), roofing and inspectors. A contractor who self-performs one of these trades needs the matching credential, or must use a licensed subcontractor.

• Roofing registration. Residential roofing requires registration with proof of general liability and workers' compensation, and commercial roofing requires an exam and endorsement. On a hail-driven rehab, this is the credential to confirm first.

• Oklahoma City. Contractors register through the city, which requires at least $50,000 in general liability and $100,000 in workers' compensation, plus the matching Construction Industries Board license for any trade work.

• Tulsa. Registers contractors through the city permit center, with its own requirements.

  A registration in one city does not transfer to another, so confirm your contractor holds the right credential for the property's location, and that the general liability behind it is high enough to matter if a worker is hurt.

How to Set the Right Limit

---

---

Insure to Completed Value

Builder's risk limits are based on the estimated completed value of the project. When the limit falls short, many forms reduce claim payments in proportion, using a simple formula: insurance carried divided by insurance required, multiplied by the loss. If a policy requires insurance equal to 80 percent of value and you carry 60 percent, you collect 75 percent of each loss and absorb the rest, even on a small claim.

Our Completed Value Worksheet

Use these lines to build the number before you request a quote:

• Rebuild cost of the existing structure. Not the purchase price and not the land.

• Full rehab budget. Materials and labor, not only materials.

• Contractor overhead and profit. These can represent up to 20 percent of completed value.

• Oklahoma code costs. Current-code upgrades on an older home, including the roof.

• Flood compliance. If the property sits in a flood zone, include any required work.

• Minus land. Land is never part of the insured value.

  ARV Is Not Replacement Cost

Investors think in after-repair value. Insurers think in rebuilding cost. ARV is a market value that includes the land and the neighborhood. Replacement cost is what it would take to rebuild the structure at current construction prices.

Use the ARV calculator for market value, and ask for a replacement cost estimate on the structure itself.

When the Loan Sets the Limit

Our fix and flip guidelines set the property limit at replacement cost, taken from the appraisal or a replacement cost estimator, or at the loan amount. If the loan amount is below replacement cost, the policy must be written on an agreed value basis or carry zero coinsurance.

When Coverage Starts and Ends

---

---

Starting Coverage

Bind coverage before you close, because your lender, or your title company on a cash purchase, will require proof of insurance. On new construction, have builder's risk in place by the time materials are delivered.

Buying Coverage in the Middle of a Rehab

You can often buy coverage after work has started, but you must disclose the work already done, and some insurers require an inspection or limit certain coverages. Expect more questions the further along the project is.

What Ends Coverage

Builder's risk ends automatically, often without a reminder, when a termination trigger occurs:

• Ownership transfers to the buyer.
• A set period passes after construction is complete.
• The property is occupied or put to its intended use.
• A single-family home is leased or rented.
• A set share of the units in a 2 to 4 unit building is leased.
• Permanent property insurance takes effect.
• Your interest in the property ends, or you abandon the project.
• The policy term expires.

The Early Tenant

On a BRRRR project, a tenant moving in can end builder's risk on the spot. On a duplex or fourplex, leasing half the units can do the same. Bind the landlord policy first.

Handing Off to Landlord Insurance

If you keep the property, put the landlord policy in effect before you cancel the old one, send the new policy details to your servicer, and send the servicer's information to the new carrier. If you sell, cancel after the transfer closes and request your pro rata refund.

How to Handle a Claim in Oklahoma

The NAIC's claims guidance lays out the core steps, and a few points matter in Oklahoma.

• Report promptly and in writing. After a tornado or hailstorm, report the claim as soon as it is safe, even if the full estimate comes later. Document the damage with dated photos before temporary repairs.

• Know your wind and hail deductible. On a storm loss, expect the percentage wind and hail deductible, not the smaller all other perils deductible, to come off the top.

• Use a registered roofer and keep the paperwork. Keep every estimate, invoice and product record, and be wary of a storm-chasing roofer who offers to cover your deductible.

• Notify your lender. The lender is usually named on the claim check, so bring it in early.

Oklahoma Playbooks by Market and Strategy

---

---

Oklahoma City Metro: OKC, Moore, Norman and Edmond

The metro combines steady flip demand with the most concentrated tornado and hail history in the state. Price the wind and hail deductible on the full limit, get the roof dried in before spring, and confirm the Oklahoma City contractor registration and roofing credential. In Moore and south OKC especially, build the storm exposure into the schedule and the reserves.

Tulsa and Northeast Oklahoma

Tulsa offers a deep supply of older bungalows and brick homes that reward a careful rehab. Hail is the recurring loss, the roof is the center of the deal, and ordinance or law coverage matters on the older stock. Confirm the Tulsa contractor registration for your crew.

College Towns: Norman and Stillwater

Norman and Stillwater carry steady rental demand around the universities, which makes the BRRRR exit attractive. Watch vacancy during summer gaps, and keep wind, hail and liability coverage in place through the hold.

Rural and Western Oklahoma: Lawton and Beyond

Rural properties can carry a higher fire protection class because they sit farther from a fire station, which raises premium, and access can slow a build. Western Oklahoma also carries grassfire and wildfire exposure in dry years. Price the protection class into the deal and keep the site secured.

Ground-Up and Infill Builds

New construction is where standalone builder's risk fits best. Insure to full completed value under the current code, put coverage in place before materials arrive and add general liability separately. Estimate financing with the construction loan calculator and our ground-up construction loan page.

BRRRR in Oklahoma

Use the rehab to set up the rental: a new roof, updated systems and a secured site before you shop the landlord policy. Get the landlord and flood quotes through OfferMarket, then run the refinance math with the DSCR calculator. Our BRRRR method guide covers the full strategy.

The Rental Exit: A Cheaper Oklahoma Landlord Policy

The rehab is the best chance to lower the cost of insuring the finished rental. Features you add while the roof and walls are open pay off in the landlord premium.

• Put on a new roof. In a hail state, roof age and condition drive the landlord premium more than almost anything else. A new, properly installed roof is the strongest move for both insurability and price.

• Document everything. Keep permits, roofing registration, product records and photos of the completed work. An insurer rating the finished rental rewards a building that is demonstrably updated.

• Bind the landlord policy before the tenant moves in. Occupancy can end builder's risk, so put the landlord insurance policy in place first, then cancel the rehab policy and request any pro rata refund. Our DWG-3 policy guide explains how landlord property coverage works.

What Builder's Risk Insurance Is

Builder's risk insurance, also called course of construction insurance, is property insurance for a building while it is being built or renovated. It covers the structure, the materials already installed and the materials waiting to be installed against losses such as fire, wind, theft and vandalism. It is temporary by design. A policy exists for one project and ends when that project ends.

---

Most builder's risk policies are written on an all-risk (open perils) basis, which means they cover any cause of loss the policy does not specifically exclude. Many also cover materials in transit and in off-site storage. There is no single standard builder's risk form, though. Two policies with the same name can respond very differently to the same loss, which is why our team reads the actual wording on every quote rather than the summary page. In Oklahoma, the wording that matters most is the wind and hail coverage and its deductible.

Oklahoma investors usually buy builder's risk in one of two ways:

• A standalone builder's risk policy insures the house and materials during the work. It does not cover injuries to other people or liability for damage to their property, so it needs a separate general liability policy beside it.

• A fix and flip policy, also called renovation insurance, combines property coverage, builder's risk features, a vacant property endorsement and general liability in one policy, with optional ordinance or law and loss of rents. For most investor rehabs, this is the better fit.

Why a Homeowners Policy Does Not Fit a Rehab

A homeowners policy is built for an owner living in a finished home. It generally does not contemplate a renovation, its additional coverages are sized for an occupied house, and it is the wrong form for an investment property in the first place. Add vacancy, open walls and stored materials, and a homeowners policy can fail exactly when you need it.

Why the Rehab Phase Is So Risky in Oklahoma

Tornado season overlaps most project timelines. With the peak of the season from April through June and the typical flip running about 161 days, an Oklahoma rehab started in late winter will almost certainly spend the most dangerous weeks under construction.

The roof is exposed when it matters most. A house mid-rehab often has an old roof, a partial roof or an open deck exactly when hail and wind are most likely.

Earthquakes add an exposure most states do not have. Oklahoma's induced seismicity means earth movement is a live question, not a theoretical one.

Terms You Will See on a Quote

Completed value. The expected value of the finished project. Builder's risk limits are usually set on this number from day one, even though the house is worth less while the work is underway.

Existing structure coverage. Coverage for the house you bought, as opposed to the new work. Some renovation policies insure only the renovation value unless you add the existing structure.

Named insured and additional insured. The named insured owns the policy, usually the LLC or person on title. An additional insured is added to someone else's policy, such as your lender on your liability policy or you on your contractor's.

Mortgagee clause and ISAOA/ATIMA. The mortgagee clause protects your lender's financial interest. ISAOA means "its successors and/or assigns," and ATIMA means "as their interests may appear." A mortgagee and an additional insured are not the same thing, and lenders usually want to be named both ways.

Wind and hail deductible. A separate, usually percentage-based deductible that applies to wind and hail losses, as explained above. In Oklahoma it is the deductible that decides what a storm really costs you.

Replacement cost and actual cash value. Replacement cost pays to repair or rebuild without deducting depreciation. Actual cash value subtracts depreciation, so an older roof or system pays out far less. On roofs especially, some carriers settle hail claims on an actual cash value basis, which matters in Oklahoma.

Functional replacement cost. A settlement basis that pays to repair with less costly materials that perform the same function. It can pay noticeably less on an older house.

Coinsurance and the 80 percent rule. Many property policies require you to insure a minimum share of value, often 80 percent. Insure for less, and the policy reduces every claim payment in proportion.

Vacancy permit. An endorsement that restores coverage a vacancy clause would otherwise take away.

Ensuing loss. Damage that results from an excluded cause. A policy may exclude faulty workmanship but cover the water damage a bad plumbing joint causes

The OfferMarket Builder's Risk Recipe

Our insurance team uses this seven-step method to structure renovation coverage for 1 to 4 unit Oklahoma investors.

---

---

1. Classify the project accurately. Cosmetic rehab, structural remodel, gut rehab or ground-up build. Disclose work already started, the vacancy history, any tenants in place and the expected timeline.
2. Set the limit on completed value. Start from the rebuilding cost of the finished house and your lender's guideline. Include contractor overhead and profit and Oklahoma code costs, and exclude land.
3. Confirm wind and hail and the deductible. No wind or hail exclusion on a financed deal, and reserves sized to the percentage deductible.
4. Close the vacancy gap. Confirm a vacant property endorsement or vacancy permit for the full rehab period, and plan heat or winterization for the cold months.
5. Add the Oklahoma coverages. Ordinance or law at 25 percent, flood where needed and earthquake where the risk warrants it.
6. Add general liability at lender limits. $1,000,000 per occurrence and $2,000,000 aggregate on an occurrence basis, with the lender as additional insured, and certificates from every contractor.
7. Bind early and plan the exit. Bind before closing, use the exact mortgagee clause with ISAOA/ATIMA, and line up the landlord policy before the tenant moves in.

Frequently Asked Questions

Do I Need Builder's Risk Insurance for a Flip in Oklahoma?

If the house is vacant and under renovation, a homeowners policy is the wrong fit, and lenders require property and liability coverage before closing. A fix and flip policy that includes builder's risk features, a vacancy provision, wind and hail coverage and general liability is the common solution.

Does Builder's Risk Cover Tornado and Hail Damage in Oklahoma?

It can, if wind and hail are included. Some vacant and renovation policies exclude the peril or offer it only as an option, and lenders require it. A separate percentage wind and hail deductible usually applies.

What Is the Wind and Hail Deductible on an Oklahoma Policy?

Most Oklahoma policies use a percentage of the dwelling limit, commonly 1 or 2 percent and up to 5 percent in higher-risk situations. On a $350,000 limit, a 2 percent deductible is $7,000. Our guideline caps it at the lesser of 5 percent or $5,000.

Does Builder's Risk Cover Earthquakes in Oklahoma?

No. Earthquake is earth movement, which builder's risk and standard property policies exclude. Covering Oklahoma's induced earthquakes means a separate policy or endorsement, with a percentage deductible that applies per event.

Does Builder's Risk Cover Flood in Oklahoma?

No. Flood, including flash flooding, requires a separate policy. In a special flood hazard area, lenders require it, and buying it at loan closing avoids the 30-day waiting period.

Do I Need a Licensed Contractor in Oklahoma?

There is no state general contractor license, but roofing, plumbing, electrical and HVAC work require a Construction Industries Board credential, and cities such as Oklahoma City and Tulsa require contractor registration. Confirm your roofer is registered before the crew starts.

How Much Does Builder's Risk Cost in Oklahoma?

It depends on the property, its location and the roof. As a guide, OfferMarket investors see roughly $1,000 to $2,000 a year on a $150,000 property with a $50,000 rehab, $1,500 to $2,500 on a $300,000 property, and $2,000 to $3,500 on a $500,000 property. Nationally, builder's risk runs about 1 to 4 percent of completed value.

Is OfferMarket Licensed in Oklahoma?

Yes. OfferMarket Insurance LLC (NPN 20545557) is licensed in Oklahoma (license number 3004490871) and in a number of other states, and it quotes, binds and services coverage. See the full list on our licenses page.
