DSCR lending qualifies investment properties based on rental income relative to the housing payment, not the borrower's personal W-2 income. Lenders calculate a Debt Service Coverage Ratio (DSCR) by dividing net operating income by the monthly PITIA payment.
How DSCR Is Calculated
Most Non-QM DSCR programs use a simplified formula:
- Monthly rent (or short-term rental revenue) minus operating expenses
- Divided by PITIA — principal, interest, taxes, insurance, and association dues
A DSCR of 1.0 means the property breaks even. Many investors target 1.25+ for stronger approval odds and better pricing.
Who DSCR Loans Are For
DSCR programs fit:
- Real estate investors scaling a rental portfolio
- Self-employed borrowers with strong assets but complex tax returns
- Short-term rental operators on Airbnb or VRBO
- Foreign nationals and ITIN borrowers (program-dependent)
What Lenders Still Review
Even with income-doc-light underwriting, expect scrutiny on:
- Credit score and housing history
- Property type and location
- Down payment and reserves
- Lease or revenue documentation
