How DSCR Is Calculated and What Lenders Require
The Debt Service Coverage Ratio for residential investment property is calculated as the monthly gross rental income divided by the monthly total housing payment (PITIA: principal, interest, taxes, insurance, and association dues if applicable).
DSCR = Monthly Rent / Monthly PITIA
A DSCR of 1.0 means the property exactly breaks even: rental income covers the full mortgage payment. A DSCR of 1.25 means the property generates 25% more income than needed to cover the payment. Most DSCR lenders require a minimum DSCR of 1.0 to 1.25 depending on their guidelines.
Some lenders offer no-ratio or negative-DSCR products for properties below 1.0, typically down to 0.75, at higher interest rates. These products recognize that investors may be willing to contribute from other cash sources if the property has strong appreciation potential.
The rental income used is the lesser of the actual current rent (from a lease agreement) or the market rent from a Form 1007 single-family rent schedule completed by the appraiser. This distinction matters: if a property is rented below market, the appraiser's market rent figure can be used instead. If the property is rented above market, the actual rent is capped at market.
Required Documentation
- ✓Current lease agreement (if property is already rented)
- ✓Form 1007 single-family rent schedule from the appraisal (appraiser completes this)
- ✓12 months of bank statements showing rental income deposits (if property is currently rented)
- ✓Entity documents if purchasing through LLC or corporate entity
- ✓Reserves: typically 6 months PITIA in verifiable liquid assets
- ✓Property insurance quote (must be landlord or non-owner-occupied policy)
What Most Lenders Get Wrong
- 1.Using the borrower's stated rent estimate instead of the Form 1007 appraiser rent schedule. The market rent from the appraisal is required and cannot be replaced by a borrower's projection or a Zillow estimate.
- 2.Calculating PITIA without the correct insurance premium for a non-owner-occupied policy. Investor property insurance is typically higher than primary residence insurance, and understating the insurance cost inflates the DSCR.
- 3.Not requiring entity documentation when the borrower is purchasing through an LLC. DSCR loans are commonly originated in entity names, but not all DSCR lenders allow it, and those that do have specific entity documentation requirements.
- 4.Treating short-term rental history as equivalent to long-term rental income without lender-specific approval. Many DSCR lenders will not count Airbnb or VRBO income at all, while others require 12 months of STR management statements.
Short-Term Rental Income and DSCR: A Lender-by-Lender Question
Short-term rental (STR) income from Airbnb, VRBO, or similar platforms is the most variable and lender-specific aspect of DSCR lending. There is no standard agency guideline because DSCR loans are non-QM products, so each lender sets its own rules.
Lenders who accept STR income typically require 12 months of management platform statements showing actual payouts, a Form 1007 from an appraiser who completes the STR addendum showing market STR income, and sometimes a third-party STR market analysis.
Lenders who do not accept STR income will base the DSCR calculation on the long-term rental market rent from Form 1007. If a property that rents for $3,500 per month on Airbnb has a long-term market rent of $2,200 per month, the DSCR is calculated using $2,200. For Bakersfield properties near tourist destinations or the lakes, this can materially affect qualifying.
For first-time STR investors without any rental history, almost all DSCR lenders use the market rent from Form 1007 as the baseline, and some require a business plan or STR management agreement.
DSCR Loan Terms, Rates, and Where They Fit in a Portfolio Strategy
DSCR loans are non-QM products, meaning they are originated by portfolio lenders who keep the loans on their own balance sheets or sell them to private investors rather than to Fannie Mae or Freddie Mac. This creates two practical differences from agency loans: rates are typically 0.5% to 1.5% higher than conventional investment property rates, and the underwriting overlays vary by lender.
The typical DSCR loan structure is a 30-year amortizing loan at a fixed rate, often with a 3 to 5 year prepayment penalty. Some lenders offer interest-only periods of 5 to 10 years, which improves cash flow during the early holding period at the cost of no principal reduction.
DSCR loans are most commonly used by investors who are self-employed with complex tax returns that show low net income after deductions, investors who own multiple properties and have reached conventional loan limits, and buyers purchasing through LLCs or other entities.
For Kern County investors, DSCR lending has been a growth area because it allows acquisition of rental properties without the income documentation friction of conventional lending. A self-employed borrower whose Schedule C shows $40,000 in net income but who is buying a property with $1,800 per month in rental income against a $1,400 PITIA has a 1.28 DSCR and qualifies without triggering the self-employment income analysis.
DSCR is the most useful tool in the investor toolkit for borrowers who cannot or do not want to document personal income for every rental acquisition. The key is matching the property to the right lender, because DSCR lender overlays vary more than any other loan type I handle. I have relationships with DSCR lenders across the spectrum from the strictest 1.25 minimum to no-ratio products for strong assets. The right match depends on the property numbers and the borrower's reserve position.
