A Debt Service Coverage Ratio loan is underwritten on the rent the property produces. No tax returns, no W-2s, no personal debt-to-income calculation — which is why investors with strong portfolios and modest reported income use them to keep buying.
Below: how the ratio is actually calculated, what underwriting will ask for, where deals usually go wrong, and a calculator that tells you whether a specific property clears.
Ranges reflect common guidelines across the lenders we work with. They are not an offer, and your file may price inside or outside them.
A DSCR loan is a mortgage on an income-producing residential property where the lender's central question is not “can this borrower afford the payment out of their salary?” but “does this property's rent cover its own debt service?” Everything else in underwriting — credit, reserves, experience, the appraisal — supports that one question rather than replacing it.
That distinction matters more than it sounds. Conventional investment-property financing counts your existing mortgages against your personal debt-to-income ratio, so each rental you buy makes the next one harder to qualify for, no matter how well the portfolio performs. DSCR underwriting evaluates each property largely on its own economics. Investors who hit a DTI ceiling at four or five properties on agency financing are frequently the same people who close their sixth and tenth on DSCR terms.
The second group these serve is self-employed owners whose tax returns are, by design, unflattering. Aggressive depreciation and legitimate write-offs are good tax strategy and terrible loan documentation. A DSCR file sidesteps the conflict: the returns never enter the analysis.
The trade is cost. Because the lender takes on documentation risk, DSCR pricing typically sits above comparable agency investment pricing, and prepayment penalties are common. On a property that cash flows, the arithmetic usually still favors the DSCR loan — but it is a real trade, and anyone who tells you otherwise is selling.
DSCR is gross monthly rent divided by the property's total monthly debt service — principal, interest, taxes, insurance, and HOA dues if any. A 1.00 means the rent exactly covers the payment. Most lenders price best at 1.20 or above, and many will still lend below 1.00 with a larger down payment.
Illustration only. Taxes and insurance estimated at 1.55% of price annually; your actual figures, rate, and qualifying rent will differ. Not a quote or commitment to lend.
Shorter than a conventional file, and none of it is about your job. Have these ready and a DSCR loan is a genuinely fast process.

Neither is better in the abstract. If your tax returns support the payment and you're under the agency property limit, conventional is usually cheaper. Past that point the comparison stops being about price.
All five are avoidable if they're caught before you're under contract.

Anything specific to your property is a five-minute phone call.
Talk it through →Yes, and most investors do. Entity vesting is standard on DSCR programs — you'll provide the operating agreement, articles of organization, and a certificate of good standing, and you'll personally guarantee the note. This is one of the clearest advantages over agency financing, which generally requires title in your personal name. Decide before the appraisal is ordered, because changing vesting mid-file causes re-disclosure and delays.
That's the normal case on a purchase. The appraiser completes a comparable rent schedule — Form 1007 — estimating market rent for the unit, and underwriting uses that figure. If the property is already leased, most lenders use the lower of the actual lease or the 1007 estimate, so an above-market lease won't help you and a below-market one will hurt.
There's no agency-style cap of ten financed properties. Individual lenders set exposure limits — often a maximum number of loans or total dollar amount with that one lender — but you can hold DSCR loans across several lenders. Investors with twenty-plus doors are routine. Once you're at real scale, a portfolio or blanket loan may beat doing them one at a time.
Often, though guidelines vary more here than anywhere else in the program. Some lenders will use documented short-term revenue — a trailing twelve months from the platform, or a market projection report; others insist on long-term market rent even for a property you intend to run nightly, which produces a very different ratio. Local rules matter too: if the municipality restricts short-term rentals, expect underwriting to ask. Tell us the intended use up front and we'll take it to lenders whose guidelines match.
Most DSCR loans carry one, commonly structured over three or five years and stepping down annually, or as a percentage of the balance paid off early. You can usually buy it down or out entirely for a higher rate. Which way to go depends on your hold plan: if there's any chance you refinance or sell inside three years, price both and compare total cost rather than defaulting to the lower rate.
Yes — cash-out refinancing is one of the most common uses, typically to 70–75% of value, and it's how most investors recycle equity into the next purchase. Two things to check: seasoning requirements, since some lenders want six months of ownership before using a new appraised value, and whether the higher loan amount still clears the minimum ratio at current rates.
Not usually for a standard single-family DSCR loan — first-time investors qualify regularly. Experience starts to matter on larger multi-unit properties, short-term rental underwriting, and any file where the lender is stretching on ratio or leverage. Where a program does require it, twelve months of owning any rental generally satisfies the guideline.
