What Is a Good DSCR for a Rental Property?

1.25 is the figure repeated across the industry, and it is a reasonable orientation: most income-property lenders want a genuine cushion rather than bare coverage.

But treat it as an expectation to confirm, not a rule. Fannie Mae states plainly that DSCR and loan-to-value requirements are subject to change based on market conditions, and that ranges vary for affordable-housing transactions. Requirements differ by lender, by programme, by property type, and over time.

The only DSCR requirement that matters for your deal is the one your actual lender states for your actual loan.

Fannie Mae's Multifamily Guide defines DSCR using *underwritten* net cash flow — underwritten effective gross income less underwritten total expenses. That word is doing a lot of work.

A lender does not simply accept your rent roll and your expense schedule. It applies its own vacancy assumption, its own expense minimums, and often its own view of achievable market rent. These adjustments are conservative by design.

The practical consequence is that an owner who calculates 1.30 may be told the lender underwrote 1.15 on the same building. That is not the lender being difficult; it is the lender applying its standard haircuts. Build the gap into your expectations before you apply.

Debt service depends on how the loan is built. Fannie Mae notes that a full interest-only loan reflects only interest in the calculation, while amortizing loans include principal and interest.

So an interest-only period produces a flattering DSCR that will fall — sometimes sharply — the day amortization begins. If you are underwriting a deal with an interest-only period, check the ratio at the amortizing payment too, because that is the payment the property has to survive.

It means the property does not generate enough income to make its own loan payments. The gap has to be funded from reserves, other income, or your pocket.

It does not automatically end a deal. Lenders generally respond by reducing the loan amount rather than declining outright — a smaller loan means smaller payments and a higher ratio. That requires more cash from you, which is precisely the point: the lender is shifting risk back until the property can carry what remains.

Raise net operating income — increase rent or cut operating expenses. This is the only lever that genuinely improves the investment rather than the metric.

Reduce the loan amount, usually by putting in more cash. Real improvement in coverage, at the cost of tying up more capital and lowering your cash-on-cash return.

Reduce the payment on the same loan, through a lower rate or a longer amortization. Be careful with the last one: stretching amortization lowers the payment and lifts DSCR while increasing total interest paid over the life of the loan. It improves the ratio more than it improves the deal.
