DSCR below 1.0: your options (what kills DSCR deals)
A DSCR below 1.0 doesn't automatically kill a rental property loan, it means the property's rent doesn't fully cover the mortgage payment on paper. You can still close the deal by putting more money down, switching to an interest-only or ARM structure, buying down the rate, using a no-ratio program that skips the DSCR test entirely, or restructuring the deal so the numbers pencil. What actually kills these files more often isn't the ratio itself, it's underestimated taxes and insurance, a missed HOA payment, or short-term rental income the lender won't count.
DSCR stands for debt service coverage ratio. Lenders calculate it by dividing the property's gross rental income by its total housing payment (principal, interest, taxes, insurance, and HOA dues if any, often shortened to PITIA). A ratio of 1.0 means the rent exactly covers the payment. Anything below that means the property doesn't cash flow on paper, even if the deal still makes sense to you as an investor.
Most DSCR lenders want to see 1.0 or higher, and some programs price better at 1.25 or above. But plenty of lenders will still approve a deal below 1.0, sometimes down to 0.75, with adjustments to price or terms. The ratio isn't a wall, it's an input that changes the loan's cost and structure.
What can you do if your DSCR comes in below 1.0?
Five levers actually move the number: a larger down payment, an interest-only or adjustable-rate structure, a rate buydown, a no-ratio program, or repricing the deal itself (renegotiating price or getting a higher rent estimate). Each one attacks a different part of the equation, either raising the income side or lowering the payment side.
Does a larger down payment fix a sub-1.0 DSCR deal?
Yes, and it's usually the most straightforward fix. A bigger down payment means a smaller loan amount, which means a smaller principal and interest payment, which raises the ratio directly. If you're a few points short of 1.0, running the DSCR calculator with a higher down payment is the fastest way to see exactly how much more equity you'd need to put in to clear the threshold. The tradeoff is obvious: less leverage, more cash tied up in one deal.
Can an interest-only or ARM loan raise DSCR?
Often, yes. An interest-only period removes the principal portion of the payment for a set number of years, which lowers the monthly PITIA and raises the ratio without changing the loan amount. An adjustable-rate structure can do something similar if its starting rate is lower than a fixed rate would be. Both come with a catch: once the interest-only period ends or the rate adjusts, the payment can rise, so this fix works best when you expect rents to climb or you plan to refinance or sell before the structure changes.
What is a rate buydown and when does it help?
A buydown means paying discount points upfront to lower the note rate, which lowers the payment and raises DSCR. It's a direct trade of cash now for a lower payment for the life of the loan (or for a temporary buydown period, cash for a lower payment in the early years). It makes the most sense when you're close to the DSCR threshold and have the cash on hand, and it's worth comparing against simply making a larger down payment, since both reduce the payment but affect your capital differently.
What is a no-ratio DSCR program?
A no-ratio program skips the DSCR calculation entirely. The lender doesn't require the rent to cover the payment at all, they just verify the property and the borrower's overall file. These programs exist for exactly this scenario, a property that will never cash flow well on paper but makes sense for other reasons (appreciation play, short hold, portfolio addition). They typically come with a rate or fee tradeoff since the lender is taking more risk without the income cushion. You can review how these sit alongside standard DSCR options in the DSCR program section of our non-QM lineup.
Can you reprice the deal instead of restructuring the loan?
Sometimes the cleanest fix isn't the loan at all, it's the purchase. If a property is priced to a DSCR near 1.0 only under optimistic rent assumptions, going back to the seller on price, or getting a fresh rent survey that reflects current market rents, can move the ratio without touching the loan structure. This is worth doing before you spend money on points or restructure into an ARM you don't want.
What actually kills DSCR deals in underwriting?
Three things show up over and over: taxes and insurance estimated too low at the purchase contract stage, an HOA payment that got left out of the initial numbers, and short-term rental income the lender won't credit.
Taxes and insurance are the quiet killers. A buyer runs their own numbers off a listing agent's estimate, and then the actual insurance quote comes in higher (increasingly common in higher-risk zones) or the county reassesses the tax bill closer to the new purchase price. Either one raises PITIA after the borrower thought they already cleared 1.0, and now the file is short.
HOA dues get missed for a similar reason: they're often not on the listing sheet, or the number floating around is outdated. Every dollar of monthly HOA goes straight into the DSCR denominator, so a few hundred dollars a month of dues can be the difference between a deal that works and one that doesn't.
Short-term rental income is the trickiest of the three. Some DSCR lenders will use projected short-term rental income (often from a service like AirDNA) instead of a standard long-term rent survey, but not all of them will, and some cap how much of that projected income they'll count. If your whole plan depends on STR income and the lender you're working with only counts long-term market rent, your DSCR can look completely different than you expected. This is a conversation to have with your loan officer before you're under contract, not after the appraisal comes back.
Sub-1.0 DSCR fix options compared
| Option | How it works | Effect on DSCR | Main tradeoff |
|---|---|---|---|
| Larger down payment | Reduces loan amount and P&I payment | Raises ratio directly | Ties up more cash, less leverage |
| Interest-only or ARM | Lowers monthly payment during IO period or intro rate | Raises ratio while structure lasts | Payment can rise later |
| Rate buydown | Points paid upfront lower the note rate | Raises ratio for loan term (or buydown period) | Upfront cash cost |
| No-ratio program | Skips DSCR test entirely | N/A, income not measured | Higher rate or fee for the risk |
| Reprice the deal | Renegotiate price or get updated rent survey | Can raise ratio without touching loan terms | Depends on seller or market rents |
A real scenario
A borrower had a rental property under contract with a DSCR that looked fine at the purchase agreement stage, comfortably over 1.0 using the rent roll the listing agent provided. By the time underwriting ran the final numbers, two things had changed. The insurance quote came back higher than the placeholder estimate used in the original application, and the HOA dues, which hadn't been listed anywhere in the marketing materials, showed up on the title report. Together, those two additions to the payment side of the ratio pulled the deal under 1.0. The borrower also wanted to run the property as a short-term rental, but the lender on the file only counted long-term market rent for qualifying, which meant the higher projected nightly income never entered the calculation at all. The fix ended up being a mix: a slightly larger down payment to bring the loan amount down, plus going back to get an updated, more accurate rent comp for the long-term rate. The lesson from that file is the one that shows up again and again: get real insurance and HOA numbers before you run DSCR, not after.
If you're evaluating an investment property purchase and want to see how sensitive your numbers are to small changes in insurance, taxes, or down payment, running a few scenarios through the mortgage payment calculator alongside the DSCR calculator will show you exactly where the pressure points are before you're locked into a contract.
Frequently asked questions
What DSCR ratio do lenders require?
Most DSCR lenders want 1.0 or higher, with some programs pricing more favorably at 1.25 and up. Many lenders will still approve deals below 1.0, sometimes down to around 0.75, with adjustments to rate, down payment, or loan structure.
Is a DSCR below 1.0 automatically a decline?
No. It changes the terms available (more down payment, a different rate, an interest-only structure, or a no-ratio program) rather than ending the deal outright. The ratio drives pricing and structure, not a strict pass/fail line at most lenders.
Does an interest-only loan permanently fix a low DSCR?
No, it fixes it for the interest-only period only. Once that period ends, the payment typically rises to include principal, which can push the ratio back down unless rents have grown or you refinance before the change hits.
Can I use projected short-term rental income to qualify?
Sometimes. Some DSCR lenders will use a short-term rental income projection instead of a standard long-term rent survey, but not every lender does, and caps vary. Confirm this with your loan officer before you count on it, since it's one of the most common reasons a DSCR estimate changes late in the process.
What is a no-ratio DSCR loan?
A no-ratio program qualifies the loan without measuring rental income against the payment at all. It's built for properties that won't cash flow well on paper but make sense for other reasons, usually at a rate or fee cost compared to a standard DSCR loan.
Why did my DSCR change between application and closing?
Usually it's the payment side, not the rent side. A higher final insurance quote, a reassessed tax bill, or an HOA payment that wasn't included in the original estimate can all raise PITIA and lower the ratio after the fact.
Does a rate buydown make more sense than a bigger down payment?
It depends on how you want to deploy your cash. Both lower the payment and raise DSCR, but a buydown spends money on a permanently or temporarily lower rate while a larger down payment reduces the loan balance itself. Running both scenarios through the DSCR calculator side by side is the fastest way to compare them for your specific numbers.
Where can I see DSCR loan options directly?
The DSCR program section of our non-QM lineup lays out how these loans are structured, and from there you can contact a loan officer to run your specific property's numbers.
