Conventional mortgage underwriting was built around W-2 employees with predictable salaries. For real estate investors—especially those who hold properties in LLCs, write off depreciation aggressively, or manage multiple properties—that model creates unnecessary friction. DSCR loans solve that problem by shifting the qualification focus from the borrower's personal income to the property's ability to generate cash flow.
What a DSCR Loan Is
A DSCR loan is a non-QM (non-qualified mortgage) product designed exclusively for investment properties. "Non-QM" means the loan does not conform to Fannie Mae or Freddie Mac guidelines, which require full income documentation and strict debt-to-income (DTI) calculations. Instead, the lender evaluates whether rental income from the subject property is sufficient to cover the loan's debt obligations.
DSCR stands for Debt Service Coverage Ratio. It measures how much income a property produces relative to what it costs to service the debt.
The formula: DSCR = Net Operating Income (NOI) / Annual Debt Service
NOI is typically calculated as gross rental income minus property taxes, insurance, and HOA fees (if applicable). Annual debt service is the total of principal and interest payments for the year.
Example:
- Gross annual rent: $54,000
- Property taxes + insurance: $6,000
- NOI: $48,000
- Annual mortgage payments: $38,400
- DSCR: 1.25
A DSCR above 1.0 means the property generates more income than it costs to carry the loan. Most lenders set a minimum DSCR of 1.20 to 1.25 for approval, though some will approve at 1.0 (break-even) with compensating factors like a higher credit score or larger down payment.
