DSCR Loans Explained: Buy Rental Real Estate Without Personal Income in 2026
What Is a DSCR Mortgage and How Does It Work?
A Debt Service Coverage Ratio (DSCR) loan is an asset-based non-QM mortgage specifically tailored for residential 1-to-4 unit investment properties. Instead of evaluating personal debt-to-income (DTI) ratios, W-2 earnings, or employment history, the lender underwrites the property ability to generate sufficient gross rental income to service its own monthly mortgage debt (PITIA).
If the monthly market rent equals or exceeds the total monthly principal, interest, taxes, insurance, and HOA dues, the loan is eligible for approval.
The DSCR Mathematical Formula Explained
Underwriters calculate DSCR using this precise actuarial formula:
DSCR = Gross Monthly Rental Income ÷ Monthly PITIA (Principal + Interest + Taxes + Insurance + HOA)
Example: A single-family rental generates $3,200 in monthly market rent (verified via Fannie Mae Form 1007 appraisal rent schedule). The total monthly mortgage payment including taxes and hazard insurance is $2,500.
DSCR = $3,200 ÷ $2,500 = 1.28x (Strong debt coverage exceeding common 1.20x lender benchmarks).
