What is DSCR?

The debt-service coverage ratio (DSCR) compares a property's net operating income to its annual mortgage payments. It tells a lender whether the rental income alone covers the debt.

DSCR loans have become popular with investors because they qualify the property, not your personal income — so W-2 pay stubs and DTI matter less than whether the deal covers its own payments.

Formula

DSCR = Net Operating Income ÷ Annual Debt Service. NOI = annual rent − operating expenses; debt service = 12 × monthly principal & interest.

How to read it

  • DSCR of 1.0 means income exactly covers the debt; below 1.0 the property doesn't cover its own mortgage.
  • Most DSCR lenders want 1.20–1.25 or higher — a cushion above break-even.
  • Raising the down payment (smaller loan) or the rent improves DSCR.

Frequently asked questions

What DSCR do lenders require?
Most DSCR lenders look for 1.20–1.25 minimum, though some go down to 1.0 (or below, with higher rates/reserves). The higher your DSCR, the better your loan terms.
Do DSCR loans check my personal income?
Generally no — that's the appeal. The loan qualifies on the property's cash flow rather than your W-2 income or debt-to-income ratio, which suits self-employed and portfolio investors.
