For small real estate investors managing a portfolio of 0–100 single-family rentals (SFRs) or 1–4 unit residential properties, understanding financing options is essential for scaling your business. One of the most effective tools available is the DSCR loan, specifically designed for investors focused on income-producing properties like single-family homes, duplexes, triplexes, or quadplexes. This article explores the DSCR loan meaning, focusing on the correct DSCR formula for SFRs (Gross Rent ÷ PITIA), and provides detailed guidance for small investors, drawing on insights from OfferMarket’s extensive DSCR lending experience to ensure accuracy and practical application.

A DSCR loan, or Debt Service Coverage Ratio loan, is a non-qualified mortgage (non-QM) tailored for real estate investors acquiring or refinancing 1–4 unit residential properties, commonly referred to as single-family rentals (SFRs). Unlike traditional mortgages that prioritize a borrower’s personal income, credit score, or debt-to-income (DTI) ratio, DSCR loans focus on the property’s rental income to determine loan eligibility. This property-centric approach makes DSCR loans ideal for small investors who may have complex income streams, limited personal income documentation, or portfolios that push traditional DTI limits.
The Debt Service Coverage Ratio (DSCR) is the key metric used to evaluate a property’s ability to generate enough rental income to cover its mortgage payments. For SFRs (1–4 unit properties), the industry-standard DSCR formula is Gross Rent ÷ PITIA, where PITIA stands for Principal, Interest, Taxes, Insurance, and Association fees (if applicable). This formula assesses whether the property’s gross rental income can cover the full cost of the mortgage, making it a critical tool for lenders and investors alike.
