What Is a DSCR Loan? How It Works, the Math, and What the Loans Look Like on a Lender's Books (2026)

How a DSCR loan works, step by step

1. You find a rental property (or already own one you want to refinance). It has to be a property you will rent to someone else, not a home you will live in.
2. The lender estimates the rent. On a purchase that is usually the appraiser's market-rent opinion on the appraisal's rent schedule; on a refinance it can also be the lease in place. Which figure is used is the lender's rule, so ask.
3. The lender computes the ratio: that rent against the payment on the loan you are asking for.
4. It checks the ratio, your credit score and your down payment against its own guidelines. It does not ask for tax returns or pay stubs; it does look at your credit report and at the cash you bring.
5. You sign that the property is a business-purpose rental you will not occupy, and you can close in an LLC.

That is the whole trade: the lender stops asking how much you earn and starts asking how much the property earns.

The formula, and why two lenders get different answers

The standard version, the one most lenders and Visio Lending's own worked example use:

DSCR = monthly rent ÷ PITIA (principal + interest + taxes + insurance + association dues)

Visio's example: rent $2,350; principal and interest $1,600, taxes $250, insurance $150, association dues $35, so PITIA $2,035; DSCR 1.15. Its second example, rent $2,100 against a PITIA of $2,235, gives 0.94: the owner covers the shortfall from other income.

Quontic Bank publishes a different method: "gross rental income minus the real estate taxes, insurance and HOA fees (if applicable) by the proposed principal and interest payment." On Visio's first example that is ($2,350 − $250 − $150 − $35) ÷ $1,600 = 1.20 (our arithmetic), not 1.15. Neither is wrong; they are different definitions, and near a lender's minimum the definition can decide the file. Our DSCR calculator runs both.

What the ratio means in practice:

The requirements each lender publishes (ratio, score, down payment, loan size) are in our DSCR loan requirements table.

Who a DSCR loan is for, and who it is not for

It fits if you are buying or refinancing a rental and:

• your personal income is hard to document (self-employed, write-offs that shrink taxable income, several businesses);
• you already have many financed properties and have hit the conventional limit;
• you want the property in an LLC from day one;
• the property's rent comfortably covers the payment.

It does not fit if:

• you will live in the property. This is not a lender preference; it is the legal basis of the loan. Under the official commentary to Regulation Z, credit on a rental that is not owner-occupied is business-purpose, and "if the owner expects to occupy the property for more than 14 days during the coming year, the property cannot be considered non-owner-occupied" (12 CFR 1026.3(a), comment 3(a)-4). Lenders make you certify it.
• you have W-2 income, good credit and only a few properties. A conventional investment-property loan is usually cheaper; see DSCR loan vs conventional mortgage.
• the rent barely covers the payment and you have no reserves. A vacancy or a repair turns a 1.0 ratio into a monthly bill.

What DSCR loans look like on a lender's books

Every lender page shows its best rate. Public filings show the average. Velocity Financial (NYSE: VEL) lends to real estate investors and files its portfolio with the SEC every quarter. Its book includes commercial property loans as well as rentals, so read it as the investor-loan market, not as DSCR alone:

Source: Velocity Financial Form 10-Q for the quarter ended June 30, 2026 (accession 0001193125-26-335807).

Two things stand out. First, the average coupon is roughly 3.5 points above the best advertised DSCR rates (Kiavi "as low as 6.125%", Lima One "as low as 6.25%", both read September 26, 2026). Advertised rates are for the strongest file: high score, low leverage, strong ratio. Second, about one loan balance in ten is seriously late in this book. That is not a loss rate: the figure counts loans 90 or more days late or on nonaccrual, many of which are later worked out. It does mean the product is priced for real risk, and that a thin ratio is not a paperwork detail.

The broadest independent data comes from KBRA, which studied more than 475,000 non-QM mortgages, $216.7 billion, in about 600 securitizations since 2015. The weighted average cumulative default rate was 3.8%, with realized losses averaging 0.03%. Alternative-documentation loans, DSCR included, defaulted about 12.9% more than full-documentation loans, and the biggest driver was credit: below a 660 score, nearly 10%; above 760, below 2% (KBRA).

Where the money comes from

DSCR loans are not bought by Fannie Mae or Freddie Mac. Lenders fund them on credit lines and then sell them, pooled, to bond investors in non-QM securitizations, or keep them, as Velocity does. That market is growing: gross non-QM securitization in 2026 had already broken the annual record before the end of the year, according to Bank of America Securities, reported by National Mortgage News. It is why DSCR terms move with the bond market, not with the Fed's headline rate alone, and why lenders price by risk tier.
