The 1.25x DSCR Rule
Most lenders require a DSCR of at least 1.25, meaning your rental income must exceed your debt obligations by 25%. This buffer protects lenders against vacancies and unexpected expenses while ensuring positive cash flow for investors.
A Debt Service Coverage Ratio (DSCR) loan is a type of non-qualified mortgage (non-QM) designed specifically for real estate investors. Unlike traditional mortgages that require extensive income verification through W-2s, tax returns, and employment history, DSCR loans qualify borrowers based on the income-generating potential of the investment property itself.
The fundamental principle is elegantly simple: if the property can pay for itself through rental income, you can qualify for financing regardless of your personal income situation. This makes DSCR loans particularly attractive for self-employed investors, those with complex tax situations, or investors who already own multiple properties and face debt-to-income ratio constraints with conventional lenders.
The DSCR Formula Explained
The Debt Service Coverage Ratio measures how well a property's income covers its debt obligations:
DSCR = Monthly Gross Rental Income / Monthly PITIA
Where PITIA represents: Principal payment, Interest payment, Taxes (property taxes), Insurance, and Association dues (HOA fees, if applicable).
A DSCR of 1.0 means the property breaks even, covering exactly 100% of the mortgage payment. A DSCR of 1.25 means rental income exceeds debt obligations by 25%, providing a cushion for vacancies, repairs, and other unexpected costs.
Sample DSCR Calculation
Single-family rental property in Phoenix, AZ
This property exceeds the 1.25 minimum threshold and qualifies for DSCR financing with competitive terms
- •Market rent verified through rental comps within 1-mile radius
- •Property taxes based on 2024 Maricopa County assessment
- •Insurance quote from investor-specialized carrier
The DSCR loan landscape has evolved significantly, with requirements becoming both more accessible and more nuanced.
Minimum DSCR Thresholds
1.25+ DSCR: Most lenders, best rates. 1.00-1.24 DSCR: Many lenders, higher rates. 0.75-0.99 DSCR: Select lenders, no-ratio programs with premium pricing.
Credit Score Requirements
Most DSCR lenders require a minimum FICO score of 660. 740+ gets best rates and up to 85% LTV. 700-739 gets competitive rates at 80% LTV. 660-699 may require 75% LTV.
Down Payment and Reserves
Standard DSCR loans require 20-25% down payment. Reserve requirements are typically 3-6 months of PITIA in liquid assets.

DSCR Loan Considerations
Qualify based on property cash flow, not W-2s or tax returns.
Unlike conventional loans capped at 10 properties, DSCR lenders impose no limits.
Many DSCR loans close in 2-3 weeks versus 4-6 weeks for conventional.
Close in an LLC, corporation, or trust to protect personal assets.
Finance single-family, 2-4 units, condos, townhomes, and even 5+ unit multifamily.
Expect rates 0.5%-1.5% higher than conventional investment property mortgages.
Minimum 20-25% down versus as low as 15% with some conventional programs.
Origination fees typically 1-2 points versus 0.5-1 point for conventional.
Many DSCR loans include 3-5 year prepayment penalties.
If your target property doesn't meet minimum DSCR thresholds, you won't qualify.
