DSCR Loan Requirements for Rental Properties

Last reviewed: 3 October 2026. Lending standards change; verify current minimums with your lender. Not financial or legal advice.

What is DSCR?

The debt service coverage ratio (DSCR) measures how much net operating income (NOI) a property generates relative to its annual loan payments. A DSCR of 1.25 means the property earns $1.25 for every $1.00 of debt service — a 25% cushion against vacancies or expense surprises.

DSCR = NOI ÷ Annual Debt Service, where NOI = Effective Gross Income − Operating Expenses and Annual Debt Service = Monthly Payment × 12.

What DSCR do lenders require?

Requirements depend on the loan program:

• DSCR rental loans (non-QM): most programs require 1.00–1.25. A minimum of 1.00 (break-even) is common for single-family rentals; 1.20 is typical for 2–4 unit properties. Rates are often higher than conventional loans to compensate for the lower threshold.
• Conventional rental loans (Fannie/Freddie): underwritten on borrower income, not DSCR. Rental income may be credited at 75% of market rent and counted toward qualifying income. No explicit DSCR minimum, but the cash-flow contribution affects the debt-to-income calculation.
• Commercial real estate loans: lenders typically require 1.25–1.35 for apartment buildings (5+ units), retail, office and industrial. SBA loans generally require 1.25 global DSCR across all business and personal obligations.
• Portfolio lenders: requirements vary. Some accept 1.0; others require 1.30. Expect higher down payment requirements when DSCR is low.

How lenders calculate DSCR

Practices vary, but the most common approach for 1–4 unit rentals:

• Income: market rent (from an appraisal or lease) × 12, sometimes discounted by a vacancy factor (5–10%).
• Expenses: lenders often use a fixed expense ratio (20–35% of gross income) rather than itemised expenses. Others use actual tax, insurance, HOA and a standard management/maintenance allowance.
• Debt service: the fully amortising monthly payment at the note rate × 12. Some lenders stress-test at a higher rate.

Because expense treatment varies, the DSCR your lender calculates may differ from this calculator's figure. Use the calculator to model sensitivities; confirm the underwriting method with your lender.

How to improve your DSCR before applying

1. Increase rent: the most direct lever. Even a $100/month increase on a $200,000 loan at 7% adds roughly 0.08 to DSCR.
2. Reduce the loan amount: a larger down payment lowers debt service. Use the DSCR calculator's "max loan at 1.25" figure to size your loan before negotiating purchase price.
3. Lower the rate: buying down the rate or shopping lenders can meaningfully reduce annual debt service on larger loans.
4. Choose a longer term: a 30-year term has a lower payment than 20 or 15 years, raising DSCR — at the cost of more total interest paid.
5. Cut operating expenses: self-managing, reviewing insurance annually, and deferring non-urgent CapEx can temporarily improve DSCR on paper, but do not cut reserves below a prudent level.

DSCR vs. debt-to-income (DTI)

Conventional loans underwrite on DTI — your total personal debt payments divided by gross income. DSCR loans underwrite on the property's income alone; your personal income is not used. This makes DSCR loans popular for self-employed investors or those with many financed properties who no longer qualify on DTI.
