Metrics
DSCR (Debt Service Coverage Ratio)
Net Operating Income ÷ mortgage payment. Measures whether the property's income comfortably covers debt service.
Lenders typically want ≥1.25 for investment loans; 1.0 means exactly break-even on debt service.
How it's calculated
DSCR = NOI ÷ Annual Debt ServiceExample
A property with $36,000 NOI and $24,000 of annual mortgage payments has DSCR = $36,000 ÷ $24,000 = 1.50.
Why DSCR (Debt Service Coverage Ratio) matters
DSCR is the constraint metric on every investment-property loan. Below 1.20–1.25, most lenders won't fund the deal at all. DSCR also tells you how much safety margin the property has.
