DSCR (debt service coverage ratio)
DSCR, the debt service coverage ratio, measures whether a rental pays for itself: the property’s monthly rent divided by its monthly payment. The payment is the full PITIA: principal, interest, property taxes, insurance and any HOA or association dues. At 1.00 the rent exactly covers the payment. At 1.20 there’s 20% more rent than payment; at 0.90 the rent falls 10% short.
A DSCR loan uses this ratio in place of your personal income, so there are no tax returns, pay stubs or debt-to-income ratio to qualify on. The ratio shapes the loan as well as the approval: a stronger one earns better pricing, and the lender’s minimum caps the payment the rent can carry, which caps the loan.
DSCR = qualifying monthly rent ÷ monthly PITIA
How lenders count the rent
Most lenders take whichever is lower: the lease you’ve signed or the market rent the appraiser estimates on the rent schedule. Kiavi lets a higher lease count up to 110% of market rent, and Roc and Civic value a vacant property’s rent at 90% of market. On a 2–4 unit property, add every unit’s rent and divide by the one payment. Short-term rentals use bookings or a projection instead; see short-term rental income.
Reading the duplex example
The leases total $2,900, but market rent comes in at $2,800, so most lenders use $2,800: $2,800 ÷ $2,375 = 1.18. Under Kiavi’s 110% rule the full $2,900 counts (110% of $2,800 is $3,080), and the ratio is 1.22. Change the payment instead of the rent and the ratio moves too: a 40-year term cuts principal and interest to $1,752 (DSCR 1.24), and a 10-year interest-only period cuts the payment to $1,659 of interest (DSCR 1.29).
What lenders look for
- 1.00 or higher opens most programs. In October 2026, conservative lenders published minimums of 1.00–1.05 (Roc and Civic 1.05). Lower floors were common too: Kiavi 0.80, LendingOne and Defy 0.75, and a few no-ratio programs with lower leverage.
- Above 1.25 is where pricing improves. LendingOne says ratios above 1.25 are often viewed favorably and those below 1.0 face added underwriting scrutiny. Below 1.00, expect a bigger down payment, a higher rate or both.
- Apartments and portfolios run stricter. Published minimums on 5+ unit loans were 1.20–1.25x. Some portfolio lenders measure net cash flow after operating expenses rather than gross rent; Roc and Civic set 1.05 on that basis.
- Commercial math is annual. On 5+ unit and commercial property, DSCR is usually net operating income divided by annual debt service: the same idea with different inputs.
- It caps the loan, not just the rate. Lenders lend the lower of their LTV limit and the loan whose payment keeps the ratio at their minimum. The DSCR calculator shows the largest loan at 1.00 and 1.25.
