DSCR
Debt service coverage ratio
DSCR is net operating income divided by annual debt service. At 1.00 the property exactly covers its own mortgage; above that there is a margin. It is the metric a commercial or DSCR-loan underwriter cares about most, because it measures the property's ability to pay the loan without the borrower's paycheque.
DSCR = NOI ÷ annual debt service
Worked example
$19,310 of NOI against $15,469 of annual payments is a DSCR of 1.25 — right at the floor most lenders quote.
Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.

Where this is calculated
