DSCR Under 1.0: Sub-Ratio and No-Ratio Programs

A broker called me on a Tuesday about a duplex. Two units, $1,950 combined market rent on the 1007, PITIA penciling at $2,210. Rent was $260 short. He had already told his buyer the deal was dead. He was calling me, he said, mostly to confirm it before he sent the cancellation.

I asked what the buyer was putting down. Twenty-five percent. Reserves? Fourteen months in a brokerage account. Credit was 752. He'd walked away from a file most sub-1.0 programs would have looked at without blinking, because somewhere along the way he'd absorbed the idea that 1.00 is a wall.

It isn't. It's a line on a pricing sheet.

What does a DSCR under 1.00 actually mean?

It means the rent does not cover the payment. That's the whole definition. DSCR is gross rent divided by PITIA, so a 0.89 says that for every dollar the property has to pay out each month in principal, interest, taxes, insurance and association dues, it's bringing in eighty-nine cents. The borrower is feeding the property eleven cents on the dollar out of pocket.

On a $2,310 PITIA, that's roughly $260 a month. $3,120 a year. Not nothing. Also not a catastrophe for an investor with real reserves and a reason to own the building.

What the ratio does not tell you is why. A 0.89 in a market where rents are climbing eight percent a year and a 0.89 on a tired fourplex in a town losing population look identical on the calculator. They are not the same file.

The DSCR calculator on our site does the division for you. Put in the 1007 rent, not the rent you hope to get after the renovation.

Why doesn't a ratio under 1.00 end the conversation?

Because the ratio is one input into a risk decision, not the decision itself. Standard DSCR programs are built around 1.00 as the qualifying line: at or above it, the property carries the loan on paper and the lender can offer top leverage. Below it, plenty of programs don't stop. They step down.

The rent doesn't cover the payment, so the lender wants something else to cover the gap. Lower LTV means a bigger equity cushion under the loan. More reserves mean the borrower can carry the shortfall for years, not months. Higher credit means a track record of paying things that were inconvenient to pay. Stack enough of those and the missing coverage stops being what sinks the file.

I've closed loans at 0.82. I've closed loans with no ratio calculated at all. I've also told people at 0.95 they were about to buy a problem.

How do sub-1.0 tiers trade LTV for coverage?

The mechanism is a step-down grid. Every program draws its own lines, but the shape is always the same: as coverage drops, maximum LTV drops with it, and the credit and reserve requirements tighten. Here is an illustrative version of what that grid tends to look like on a purchase.

Illustrative only. Every lender's grid is different and they change. The floor across all of it is a 640 credit score.

Now the arithmetic. Take a single-family rental at a $310,000 purchase price. The 1007 comes back at $2,050 market rent. With taxes, insurance and a small HOA, the PITIA at 75% LTV pencils to $2,310.

$2,050 divided by $2,310 is 0.887. Round it to 0.89. That file lands in the middle tier. Max LTV drops from 75% to, say, 70%, so the loan goes from $232,500 to $217,000 and the down payment goes from $77,500 to $93,000. The buyer needs another $15,500 at closing and probably another six months of reserves on top of what a 1.00 file would have asked for.

Here's what people miss. The smaller loan also shrinks the PITIA. Same taxes, same insurance, same HOA, but less principal and interest. At 70% LTV the PITIA might settle around $2,190. Run the division again: $2,050 over $2,190 is 0.94. Still under 1.00, still in the sub-ratio tier, but the monthly shortfall went from $260 to $140. Drop to 65% and the ratio can crawl back toward 1.00 on its own, at which point the file might price as a standard DSCR loan and the whole sub-ratio question goes away.

That's the real trade. You're buying the ratio up with equity. Whether it's worth doing depends on what the extra $15,500 would have earned somewhere else, and only the investor can answer that.

Pro Tip: Before you accept the sub-ratio tier, ask what LTV gets the file to 1.00 on the lender's own PITIA. Sometimes the answer is two or three points of leverage, and standard pricing is cheaper than sub-ratio pricing by more than that equity costs you.

What does a no-ratio DSCR program look at instead of rent?

It skips the rent test. There's still a 1007 in the file, there's still an appraisal, but the lender doesn't calculate coverage and doesn't condition the approval on it. The property has to be a legitimate non-owner-occupied investment, and the loan is still business-purpose. What changes is the underwriting weight.

Down payment carries most of it. No-ratio programs sit at the low end of the LTV grid, commonly 60% to 70% on a purchase, sometimes lower on a cash-out. The lender is betting on equity, not cash flow.

Reserves carry the rest. Twelve months of PITIA is a normal ask. Some programs want more. The theory is that if the property runs negative, the borrower has already proven they can run it negative for a year without touching the payment.

Credit sits on top. 700 is a realistic entry point for most no-ratio tiers and 740 gets the best terms. The 640 floor technically exists across DSCR lending but it is not where no-ratio pricing lives.

Who uses these? Investors buying vacant property that needs work before it will rent. Short-term rental buyers where the 1007 long-term rent is a fraction of what the property actually earns. Cash-out borrowers on a paid-off building where the rent is fine but the new PITIA isn't. And people like the broker's duplex buyer, who had the equity and the reserves and needed a program that valued them.

Seasoning still applies on refinances. No-ratio doesn't waive that clock; the seasoning post covers it.

Why is the pricing higher on sub-ratio and no-ratio loans?

The rate is higher. It should be. The lender is taking the risk the property isn't taking.

On a 1.20 file, the tenant makes the payment. On a 0.89 file, the tenant makes most of it and the borrower's checking account makes the rest, every month, for as long as the gap exists. If the borrower loses a job, gets divorced, has a bad year in their main business, the property doesn't bail them out. It's one more bill. Lenders price that. They'd be foolish not to.

The premium shows up as rate and as a tighter box: lower LTV, more reserves, higher credit minimums, sometimes a longer prepayment penalty with fewer ways to buy it out. Prepay terms vary by state and by program, and that's a conversation for the specific file.

I'd push back on the idea that the premium is punitive. The alternative is no loan. Or hard money at a price that makes sub-ratio DSCR look like a gift. Or a full-doc investment loan that drags the borrower's tax returns into it, which is what most DSCR borrowers are trying to avoid. Against those, paying more for long-term financing on a property that doesn't quite cover itself yet is a reasonable trade for the right investor.

For the wrong investor, it's expensive rope.

Why is the ratio short in the first place?

This is the question I actually care about, and it's the one nobody asks. A 0.89 has a cause. The cause matters more than the number.

The market is ahead of the rents

Some markets run hot on price for years before rents catch up. Purchase prices move on buyer demand, interest, and speculation. Rents move on what a tenant can pay from a paycheck. When those two diverge, you get a whole metro where a freshly bought rental at 75% LTV pencils to 0.85 on day one and 1.05 three years later.

That's a defensible sub-ratio file. The borrower isn't buying a bad property. They're buying early. The lender's job is to make sure they can carry it until the rents arrive, which is why the reserve requirement in that tier is doing real work.

A legacy tenant is paying 2019 rent

I see this constantly on small multifamily. The seller has had the same tenant in the upper unit for nine years and never raised the rent because they liked them. Actual rent is $1,400. Market rent on the 1007 is $1,900. The appraiser will typically use market rent on a purchase, so the ratio may be fine on paper, but if the lease is long or the lender uses the lower of lease and market, the file lands under 1.00 for reasons that have nothing to do with the building.

That's a timing problem, not a property problem. The buyer either brings the unit to market at turnover or negotiates the price down to reflect the gap. Either way, the sub-ratio tier is a bridge, and the 1007 post covers how the appraiser arrives at the number the lender actually uses.

The property doesn't work

Then there's the third case. The rents are already at market. There's no upside tenant to turn over. The neighborhood isn't appreciating. The taxes are high and the insurance just doubled and the ratio is 0.79 because the property is a 0.79 property. It was a 0.79 property when the seller listed it and it will be a 0.79 property when the buyer tries to sell it in five years.

A no-ratio program will still lend on that. The equity is there, the reserves are there, the credit is there. Nothing in the guidelines stops it.

I would.

When is the honest answer "don't buy it"?

When the shortfall has no exit. That's the test. Every sub-ratio loan I'm comfortable with has a story for how the ratio gets to 1.00 or better, and the story has a date on it. Rents catch up by 2028. Tenant turns over next spring. Renovation finishes in ninety days and the unit goes from $1,400 to $2,100. Something.

If the story is "I'll just cover the difference," ask for how long. Forever is not a plan. A $260 gap on one property is manageable. Four of them is $1,040 a month, and some people call that a portfolio.

Watch taxes and insurance separately from the rent. Rent can go up. Taxes and insurance go up too, and in a lot of markets right now they're moving faster. A 0.89 that depends on rent growth can turn into a 0.84 when the insurance renewal comes in ugly.

Look at the appreciation case with a cold eye. Plenty of investors buy negative cash flow on purpose because equity growth pays for it. Legitimate in the right market. Speculative everywhere else, and a sub-ratio loan on a property that isn't appreciating is a slow way to lose money with a monthly reminder.

And check the reserves against reality. Twelve months of PITIA sounds like a lot until the roof turns out to be fourteen years old. The lender's reserve requirement is a floor, not a budget.

Pro Tip: Run the ratio at a PITIA that assumes a 15% jump in taxes and insurance. If the file still makes sense to you at that number, the sub-ratio tier is doing what it's supposed to do. If it doesn't, the ratio wasn't the problem.

What does a sub-ratio or no-ratio file need to show?

More of everything the standard file shows, plus a reason the ratio is short. The DSCR program page covers the base requirements. Below 1.00, expect the down payment sourced and seasoned, reserves verified in liquid accounts rather than retirement funds at a haircut, and a 1007 that gets read even when nobody's dividing by it.

If the property is one piece of a larger strategy, say so. Six performing rentals at 1.15 and one at 0.89 is a different credit than a first-time investor at 0.89, and most programs know it. That's how the whole non-QM product line works: the file gets underwritten on what's there, not on one ratio.

The broker's duplex closed, by the way. 70% LTV, sub-ratio tier, buyer brought an extra $18,000 to the table and kept the reserves intact. The lower unit turns over in March and market rent puts the property at 1.03. He sent the cancellation to his own drafts folder and left it there.
