The Quick Read: A DSCR lender sizes a second home turned short-term rental by taking the smaller of two numbers: the loan the property’s rental income can support, and the loan the leverage cap allows. The loan is no longer a second-home loan once rental income drives lender review. It becomes investment financing, reviewed on the property rather than the borrower’s paycheck.
- Rental income, not personal income, carries the file, subject to lender guidelines.
- On short-term rentals, the network’s programs typically reach up to 75% LTV on a purchase and up to 70% on a refinance or cash-out.
- Coverage of 1.00 is where short-term-rental purchase and refinance programs start. Stronger ratios open better terms.
- A 640 credit score and about 12 months of hosting experience are typical expectations.
- Clearing the ratio does not mean the property cash-flows.
Plenty of owners buy a lake cabin or beach condo for family use, then realize the calendar has open weeks. Renting those weeks is easy. Financing around that income is where the rules change, and the sizing logic is worth knowing before a file is submitted.

As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
Why Does a Second Home Stop Being a Second Home?
The label follows the income. Agency second-home loans carry a rider requiring the borrower to keep exclusive control of the property. Per Nolo, the home cannot sit in a rental pool or under an agreement that hands occupancy decisions to a manager. A Freddie Mac second-home guideline summary at Homebuyer.com adds that rental income from such a property cannot be used to qualify.
So an owner who wants Airbnb income counted has a choice. Keep the second-home label and count nothing, or move to investment treatment and count the income. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Here’s the catch. The tax view and the mortgage view of “second home” don’t match. A commentary glossary at AdviceOnly notes that tax treatment tolerates heavy rental use while the mortgage definition does not. Tax treatment varies; consult a qualified professional.
Across the wholesale network, a refinance of an existing second-home mortgage into a DSCR loan simply replaces that loan. The second-home label comes off. For the broader mechanics, the complete DSCR loans guide covers the product end to end.
Step One: How Is Qualifying Income Established?
Lenders use one of three income sources, and which one applies depends on the property’s history.
| Income source | Best for | Main risk |
|---|---|---|
| Appraiser rent schedule | Properties with no hosting record | Reflects long-term rent, often below short-term potential |
| Market projection | Purchases with no history | Describes a typical property, not yours |
| Trailing history | Former second homes already hosted | Seasonal swings in the trailing months |
The appraiser’s rent schedule (Form 1007 on a single-family home) documents monthly market rent. It does not prove short-term income. If a program relies on it alone, a strong short-term rental can look weak on paper.
Market projections come from third-party data tools that forecast revenue by address. Lenders treat them as support, not proof. They are generally a purchase tool. On a refinance, most programs want actual history: platform statements, a manager report, or bank deposits.
The program choice matters as much as the property. Most programs we place files with accept platform history. A few lean on the appraiser’s schedule. The same house can clear one program and miss another.
Step Two: What Is the Haircut?
Gross revenue is not qualifying revenue. Lenders trim short-term income with an expense or vacancy factor before running the ratio. No federal rule sets that factor. Each program’s guidelines do, and a documented 12-month history is generally treated more favorably than a projection.
Think of it as the lender admitting that gross bookings never reach the bank untouched. Platform fees, cleaning, vacancy and seasonal troughs all take a bite. Because the factor varies by program, comparing two lenders on headline leverage alone misses half the story. Compare how each counts the income.
Step Three: What Goes in the Denominator?
The ratio divides qualifying income by the full monthly obligation: principal, interest, taxes, insurance and any HOA dues, together called PITIA. Nothing is excluded to flatter the result.
Run it conceptually. If the trimmed monthly revenue is twice the full obligation, coverage is 2.00. If the trimmed revenue only matches the obligation, coverage is 1.00. Within the network, short-term-rental purchase and refinance programs both start at 1.00. A separate path below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
A larger down payment lowers the monthly obligation and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Step Four: How Is the Loan Actually Sized?
This is where most explanations stop short. Qualifying is a yes-or-no test. Sizing is a ceiling, and two ceilings apply at once.
The income ceiling. Work backward from qualifying income. At the lender’s minimum coverage, only so much monthly obligation fits, and that caps the loan the rent can carry. Higher coverage requirements shrink it.
The leverage ceiling. Across the network, short-term-rental programs typically reach up to 75% LTV on a purchase, and up to 70% on a refinance or cash-out on short-term-rental collateral. Standard long-term rentals run higher on cash-out, up to 75%, but that figure does not describe a short-term rental.
The loan amount is whichever ceiling is lower. Picture a purchase priced at $500,000. Leverage alone would allow up to 75% LTV. If the trimmed revenue only supports a smaller loan at 1.00 coverage, the income ceiling governs, and the buyer brings more cash. In a high-priced vacation market, that is the more common outcome. Expensive cabins and beach condos often hit the income ceiling first.
(Loan size also matters at the edges. Standard programs run up to $3,000,000, and smaller balances route through select lenders in the network.)
The strongest files clear both tests: enough equity and enough rental coverage.
What Happens When the Income Sources Disagree?
Say the appraiser’s long-term rent implies thin coverage, while the market projection implies comfortable coverage. Which governs?
It depends on the program and the file. A program that accepts hosting history lets documented platform income govern once it exists. For a purchase without history, a program may blend the projection with the appraiser’s analysis, and the more conservative number tends to win when the gap is wide. Some programs credit the lower of the two. This is why an investor with a seasoned listing and 12 months of statements often has more options than a buyer relying on forecasts.
Picture three versions of the same lakehouse. With no history, the file leans on the projection and appraisal. With one season of history, it is a thin record, and lenders may still want the full year. With a full year of statements, the income is documented, and that file usually sizes most cleanly. Same house, three different conversations.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where the General Rule Breaks
- Programs that bar short-term income. If a program counts long-term rent only, a strong short-term rental can fail on paper while a different program passes it.
- Management or rental-pool arrangements. These disqualify agency second-home treatment, but they do not bar a DSCR investment loan.
- Multi-unit properties. A property with more than one unit can never be an agency second home. Two-to-four-unit properties are appraised on a different form (Form 1025).
- Hosting history. Programs typically expect about 12 months of host experience. Short-term-rental programs also expect a 640 credit score as a typical minimum.
- Ineligible property types. Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs. A rustic cabin that happens to be a log home is out, however good the bookings look.
- Compliance documents. The file typically needs any required short-term rental permit or license, plus HOA or condo documents confirming rentals are allowed. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Does Clearing 1.00 Mean the Property Cash-Flows?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, cleaning, utilities and capital expenses sit outside the calculation. A short-term rental can clear coverage and still lose money in a slow quarter.
This is the gap between qualifying and investing. Whether to buy is a separate question from whether a lender will size the loan. An investor reaching for the highest leverage a property allows should stress-test occupancy well below the projection first. If the deal only works at peak bookings, the ratio is flattering a fragile investment.
What Does the Borrower Still Document?
Personal income is not the basis. Personal debt-to-income is not tested. The borrower still provides credit, reserves, entity details if the property is held in an LLC (subject to lender program eligibility), insurance, and the property’s compliance paperwork.
Reserves vary by lender, leverage, loan size and transaction type. Many files see around six months of PITIA, with higher loan sizes stepping up. Moving from second-home to investment treatment typically means a larger down payment, more reserves and different pricing than the second-home loan carried. The trade is that the income gets counted.
Compare whether a second-home mortgage or a DSCR loan fits a short-term rental before choosing a financing path.

Frequently Asked Questions
Can I count Airbnb income if the property is still my second home?
Not on an agency second-home loan, where rental income cannot be used to qualify. To have the income counted, the loan moves to investment treatment. Many owners refinance into a DSCR loan once the property is being hosted.
Does a purchase need hosting history?
Not always. A purchase with no history can lean on a market projection or the appraiser’s analysis, subject to program rules. A refinance typically wants actual history, such as platform statements or deposits.
Is a coverage ratio below 1.00 ever possible?
Yes, through select lenders in the network, with leverage and terms adjusted. Many short-term-rental programs start at 1.00 for both purchases and refinances, so a sub-1.00 file is a different path, not a loosened version of the same one.
Which limit usually decides the loan amount on a vacation property?
In higher-priced vacation markets, the income ceiling often binds first, because trimmed revenue does not always support the full leverage cap. On a lower-priced property, the leverage cap may decide instead.
Do I need traditional personal-income documentation or W-2s?
The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, reserves and property documents still apply.
