The debt service coverage ratio is how a rental property qualifies itself. It is the reason an investor with complicated tax returns can still finance a portfolio, and it is the number that decides whether your bridge loan has a refinance to land on. It is also simple arithmetic that borrowers routinely get wrong in their own favor. Here is the calculation, line by line.
The ratio in one sentence
DSCR divides the income a property produces by the debt payment that property has to make. Above 1.0 means the property covers its own payment. Below 1.0 means it does not and the shortfall comes from you.
That is the whole concept. Everything else is a question of what counts as income and what counts as the payment, and lenders differ on both.
What goes in the numerator
The income the property generates, as the lender will document it.
The rent. On a leased property, the lender generally takes the lower of the actual contract rent and the market rent supported by the appraisal. On a vacant property or one being repositioned, the appraiser’s market rent opinion carries it.
Other recurring income. Parking, storage or laundry where it is genuinely recurring and documentable.
On residential rental files, many lenders work from gross rent against a payment that already includes taxes, insurance and any association dues. On commercial and larger multifamily files the numerator is usually net operating income, which is gross income less vacancy and operating expenses, before debt service. Those two conventions produce very different numbers, so the first question to ask any lender is which one they use.
What does not go in: your salary, your other properties’ income or appreciation. This is a property level test.
What goes in the denominator
The debt service on the new loan, as the lender calculates it for qualifying purposes.
On a residential DSCR file that typically means principal, interest, taxes, insurance and association dues. On a commercial file it is usually the annual debt service on the proposed loan.
Two details move this number more than borrowers expect. Whether the qualifying payment is amortizing or interest only, since an interest only payment is smaller and produces a higher ratio. And whether taxes are calculated on the current assessment or on a reassessment following the purchase, which on a property that has not changed hands in years can be a large difference. Ask both questions before you rely on your own math.
Reading the result
A ratio above 1.0 means the property covers its debt. Programs set their own minimum, and it can sit below 1.0 on some products, which is a way of saying the lender will accept a property that needs a small contribution from the borrower when the rest of the file is strong.
Our rental DSCR program publishes 5, 7, 30 and 40 year fixed terms, LTV up to 80%, rates from 6.50% on the Non-QM tier, a minimum credit score of 620, non-owner occupied occupancy and first time investors allowed, with short term rental income permitted. The rental portfolio and multifamily term products sit on the same program, with landlord experience required.
Why the ratio and the leverage cap fight each other
Every DSCR loan is sized by two constraints, and the smaller result wins.
The first is the leverage cap: the published LTV against the appraised value. The second is the coverage test: the largest loan whose payment the income can still cover at the required ratio.
On a high value property with modest rent, coverage binds first and you will be offered less than the LTV cap suggests. On a property with strong income relative to price, the LTV cap binds and the extra coverage simply makes the file comfortable. Knowing which one binds on your property is the difference between a refinance that works and one that arrives short. Our post on exit strategy covers why this matters most to anyone holding a bridge loan.
How to raise a ratio that falls short
Borrow less. The direct lever. A smaller loan means a smaller payment and a higher ratio, and it is how most shortfalls actually get solved.
Document the income properly. A signed lease at market, a clean rent roll, and evidence for any other recurring income. Income that exists but is not documented does not count.
Check the structure. Whether the qualifying payment is interest only or amortizing, and over what period, changes the denominator. Ask what the program allows.
Raise the rent legitimately. A below market lease on a property being repositioned is an opportunity, but the new rent has to be real and documented at the time of underwriting, not projected.
Look at short term rental income. Our program permits short term rental income, which on the right property in the right location is materially higher than a long term lease. The trade is volatility and documentation, and it is covered in short term rental loans.
Reconsider the property. The least popular answer and sometimes the correct one. A property whose income cannot cover its debt at sensible leverage is telling you something about the price.
Where DSCR fits in a plan
For most investors the DSCR loan is the destination rather than the starting point. You buy and improve with a short-term loan, then refinance into long-term debt once the property is finished and rented.
That means the DSCR test should be run before the purchase, not at the refinance. Take the projected finished value, apply the published LTV cap, check the projected rent against the coverage requirement, and confirm the resulting loan repays the bridge. If it does not, you have found the gap early, which is the whole point.
