You've got two Airbnbs running — one in Fremont, one in Green Lake — and both pay for themselves. A third property just hit your radar, and the numbers look good. Then your W-2 ruins the conversation.
On paper, you've already borrowed as much as a conventional lender allows. Your debt-to-income ratio says stop, even though the properties themselves cover their own mortgages with room to spare. That's the exact moment someone at a real-estate meetup says "DSCR loan" like it's a password.
Roughly, the pitch is true: with this loan, the property qualifies itself. Not you. The details — what lenders actually check, how Seattle's short-term rental rules bend the numbers, and where this loan gets expensive — deserve a closer look.

What is a DSCR loan, exactly?
DSCR stands for debt service coverage ratio. It's a mouthful, but the idea is simple: instead of asking whether you earn enough to cover the mortgage, the lender asks whether the property earns enough to cover it.
That's the whole trick: most DSCR programs don't verify your personal income with tax returns or W-2s. If the rent covers the payment with margin to spare, you're fundable — even when depreciation and write-offs make your tax return look modest. Self-employed investors with lumpy income love these loans for exactly that reason.
The tradeoff: the lender takes more property risk, so the terms cost more. Higher rate, bigger down payment, shorter leash.
How the DSCR calculation works
The ratio itself is one division problem:
DSCR = monthly rental income ÷ monthly PITIA
PITIA means principal, interest, property taxes, insurance, and association dues — the full monthly cost of carrying the property. Say a Capitol Hill condo rents for $3,400 a month and the PITIA totals $2,720. That gives you 1.25. The income covers the payment one-and-a-quarter times over.
Lenders typically want that ratio at or above 1.0 — the property at least breaks even on paper. Many reserve their best pricing for 1.20 to 1.25 and up. Some programs will still lend below 1.0 if you bring a bigger down payment, but expect worse terms. None of this is a law of nature; it's program-by-program, lender-by-lender. The ratio is the language they all speak, even when the dialects differ.
Here's the part that trips up Seattle STR buyers: which "rental income" number goes on top. Your Airbnb might gross $6,500 a month. The appraiser's rent schedule might say the same unit would fetch $3,800 as a long-term rental. Plenty of lenders just use the lower number. Your 1.3 ratio can become a 0.95 in the lender's spreadsheet without the property changing at all.
What do DSCR lenders typically look for?
No two programs are identical, but the pattern is consistent. Here's what lenders typically check — framed as tendencies, not universal rules.
Credit score. Most programs start in the mid-600s, with meaningfully better pricing in the 700s. Below the mid-600s, you're in hard-money territory.
Down payment. Expect 20 to 25 percent as standard. Some programs advertise less, but the rate and fees climb fast.
Reserves. Lenders typically want six months of mortgage payments sitting liquid after closing — twelve on larger loans or weaker ratios. Often a hard condition of funding.
Property type. One-to-four-unit residential is the bread and butter. Condos get extra scrutiny because the lender reviews the HOA's financial health closely. Five-plus units and mixed-use exist, but the program menu narrows.
Income documentation. Long-term rentals: usually a current lease. Short-term: typically twelve months of platform statements, or the appraiser's market-rent opinion. New to STR? Some lenders underwrite long-term rent and ignore your projections entirely.
Entity and exit. Many DSCR loans close in an LLC. Prepayment penalties are common — often one to three years — because the lender wants to keep the higher-rate loan a while. Interest-only options exist, which juices the ratio but skips principal paydown.
Your personal debts generally don't enter the picture. That's the point of the product.
Can you use a DSCR loan for an Airbnb in Seattle?
Yes, in principle. A DSCR loan in Seattle works the same way — but the city adds friction on both the lending side and the city side, and you should price both in.
On the lending side, short-term income is seasonal and lenders know it. A West Seattle beach condo might print money from June through September and limp through February. Underwriters deal with this by averaging twelve months of history and sometimes applying a haircut on top. If you're buying a property with no STR track record, assume the lender underwrites long-term market rent until you prove otherwise. We've onboarded Ballard and Capitol Hill units where the appraiser's market-rent figure landed roughly 30 percent under the actual Airbnb run rate — and the lender used the appraisal. Budget for that outcome, not the best one.
On the city side, Seattle's rules shrink the income side of your ratio. As of 2026, operators are capped at two dwelling units — one must be your primary residence. The operator license runs $75 per unit per year, plus a business license tax certificate, $1 million in liability insurance, and your license number on every listing. Platforms pay the city $4 per booked night per unit, a cost that works its way into pricing. Non-primary units also fall under the city's rental registration program, and the legislature has debated letting cities add up to 4 percent in local STR taxes.
None of this kills the strategy. It just means the lender's ratio uses smaller, more conservative numbers than your agent's pro forma. If the deal still clears 1.2 on the lender's math, you've found something real.

Where DSCR loans get expensive — and when to skip them
Bluntly: DSCR rates typically run half a point to a point and a half above conventional. Refinancing out in year one can cost real money under the prepayment penalty. And the 20-to-25-percent down payment ties up capital.
So when does it make sense? When your W-2 can't carry another conventional mortgage — you're self-employed, you've hit the loan count cap, or your tax returns show far less than your cash flow. When you're buying in an LLC. When you want your personal income out of the file.
Skip it when your income qualifies for conventional — almost always cheaper. When the property barely covers its payment at 1.0, the higher DSCR rate pushes it underwater. Refinancing within a year or two? Read that penalty clause three times.
One more honest take: don't pay a full point of extra rate just to avoid showing tax returns you could show. That's an expensive privacy preference. Use this tool where it fits — investors whose income looks nothing like their cash flow — and don't force it where it doesn't.
The revenue side of the ratio is where Seattle investors most often fool themselves, by the way. A realistic income picture matters more than the loan product. That's worth a separate conversation — our piece on cash flow versus appreciation digs into how to think about what a Seattle rental actually earns once the optimism wears off.
FAQ
What is a DSCR loan?
It's an investor mortgage that qualifies you on the property's rental income versus its debt payments — not your personal income. The lender computes a debt service coverage ratio (income ÷ PITIA) and typically wants it at or above 1.0.
Can you use a DSCR loan for an Airbnb?
Generally yes, but expect friction. Lenders often haircut short-term income or underwrite the appraiser's long-term market rent instead. In Seattle, the two-unit operator cap and licensing costs shrink the income side of the ratio further.
What DSCR ratio do lenders require?
Lenders typically want at least 1.0, with the best pricing reserved for roughly 1.20 to 1.25 and up. Some programs accept below 1.0 with a bigger down payment. It's program-by-program — no universal cutoff exists.
Do DSCR loans require tax returns?
Most programs don't verify personal income with tax returns or W-2s. That's the appeal for self-employed borrowers. You'll still document the property's income, your credit score, reserves, and the down payment.
Are DSCR loan rates higher than conventional loans?
Typically yes — often by half a point to a point and a half. You're paying for looser documentation and added lender risk. If your W-2 qualifies you for conventional financing, that's usually cheaper.
Lending criteria differ by lender and change often — nothing here is a quote or a guarantee. Before you structure an offer around a DSCR loan, get actual terms from a mortgage lender and run them past your CPA.
