DSCR Loan Risks: Why These Deals Go Bad

Serious delinquencies on DSCR loans have roughly quadrupled since the middle of 2022. That figure comes from Cotality, whose data was reported in December 2025, and "serious" there means a loan at least 90 days late or already in foreclosure.

The share of securitized DSCR loans sitting in that bucket moved to roughly 2%, a small slice of the dollars outstanding. Around 98 of every 100 of these loans are paying as agreed. A quadrupling off a very low base is still a low number.

What matters is the direction, and the pattern underneath it, because the pattern is boring. These deals did not fail on exotic risk. They failed on a rent assumption.

What the delinquency data actually says

Two things moved at once. Delinquencies climbed while rent growth collapsed underneath them.

The rent side is measurable and public. Single-family rents rose 1.4% year over year in August 2025, which Cotality called the lowest annual growth in more than fifteen years, against roughly 3% the year before. By October the same index was up 0.9%, its slowest pace since the years after the 2008 crisis. Several large metros went negative.

Now put a deal underwritten in 2021 or 2022 against that. It assumed rents kept climbing at the rate they had been climbing. They stopped. The property did not change, and the number holding it up came in lower than the spreadsheet said it would.

Why these deals went bad

The reporting around the delinquency data points at a consistent set of practices. Rent targets were set at the optimistic end of a comp range and files moved quickly. Some properties were financed where the rent at origination did not cover the monthly payment, on the theory that it soon would.

That last one deserves a hard look, because it is the whole story compressed. A deal that does not cover its payment on day one is a deal betting on rent growth to bail it out. When rent growth arrives, the bet pays and everyone remembers it as skill. When rent growth goes to 0.9%, the bet is a shortfall you fund out of pocket every month.

Underwriting standards vary across lenders and always have. The part you control is how honestly you run the numbers before you sign, which is where the rest of this is aimed.

The rent assumption is where it starts

Here is what thin coverage looks like in practice. Say the rent is $2,000 and the full monthly payment including taxes and insurance is $1,800. That is a 1.11 ratio, comfortably approvable at most programs, and it feels safe.

Run a normal year through it. One vacant month between tenants drops your annual rent to $22,000 against $21,600 of payments, so the ratio falls to 1.02. Adjust the rent to $1,900 because the market softened, keep the same single vacant month, and you land at 0.97. The property is now losing money across the year, and nothing unusual has happened to it.

That is the mechanism behind the delinquency numbers. The ratio a lender approves is a snapshot at origination, with the property full and the rent at today's number. Your actual year has vacancy in it, and a turnover, with the make-ready cost that comes attached.

How to underwrite yourself honestly

Run the property at numbers you would defend to someone skeptical, then see whether it still works.

• Use the rent a comparable unit is leased at today, not the top of the range and not what the listing asks
• Put vacancy into the annual math as a real cost, because a turnover between tenants is ordinary rather than exceptional
• Carry management at market cost even when you self-manage, since your own time is the thing you are quietly spending
• Fund a repairs and capital reserve on a schedule, so the roof is a line item instead of an emergency
• Test the deal at a lower rent and see what breaks, which tells you how much room you are actually buying

The DSCR calculator runs the ratio and shows the payment underneath it, so you can move the rent down and watch what happens to the coverage. For the full sequence to run before you offer, see how to analyze a rental deal. A deal that survives a rent cut and a vacant month is a deal that survives a soft market, and the last few years were a soft market for rents.

Coverage above the approval line is the cushion that decides whether a bad quarter is an inconvenience or a default.

Where a no-ratio loan fits, and where it does not

A no-ratio DSCR loan qualifies without the rent covering the payment, which sits close to the practice the delinquency reporting criticizes. Both of those things are true at once, and what separates them is not the product.

A no-ratio loan makes sense when you know the number and have a plan for it. A property mid-turnover that will rent well once it is ready, where you hold the cash to carry it in the meantime. A borrower whose reserves are deep enough that a few months of shortfall is a line in a budget rather than an emergency. The coverage gap there is temporary, priced, and funded.

It fails when it gets used to make a deal that does not work look like a deal that does. If the answer to "what covers the gap until the rent does" is "the rent will go up," the loan is not the problem with that deal.

What to do if your ratio is already thin

Look at the actual number. Pull your real collected rent for the last twelve months, not the lease amount, and set it against the full payment including taxes and insurance. If that lands under 1, you have a monthly shortfall you are already funding, and knowing its size beats sensing it.

From there the options are ordinary. Raise income where the market supports it, or cut a cost that is not buying you anything. Refinancing to a lower payment works if there is equity and the rate environment allows it. Selling into a market that still has buyers is a legitimate outcome rather than a failure. When none of those close the gap, call the lender early, because a servicer has far more room to work with at day 30 than at day 120.

For the mechanics of the ratio itself, how to calculate DSCR walks through the arithmetic. To see where a specific property prices out, run your numbers.

The product works. It qualifies on the property instead of your tax returns, which is useful to people whose returns understate what they earn. What the last three years demonstrated is that the underwriting test is the protection, so running it honestly on yourself before a lender runs a friendlier version is how you stay in business.
