What is DSCR?

Debt Service Coverage Ratio (DSCR) measures whether a rental property's income covers its mortgage payment. Lenders use DSCR to qualify investors for rental property loans without relying on personal income verification. A DSCR of 1.25 means the property generates 25% more income than the mortgage requires.

DSCR = Net Operating Income / Annual Debt Service

DSCR loans have become the go-to financing for rental investors who cannot qualify through traditional income documentation. Understanding DSCR helps wholesalers market deals to leveraged buyers by showing that the property qualifies for financing.
