The Quick Read: When a short-term rental has no booking history, the lender qualifies the file on a projected income figure, and if that figure drops, the coverage ratio drops with it and can push the loan below the program floor. Across Lendmire’s wholesale network, the projection gets reviewed and reduced before it is divided by the full monthly payment. Here is what matters most:
- A purchase with no history can qualify on a projection, an appraiser’s short-term rental analysis, or the long-term rent schedule, depending on the program.
- Short-term rental purchases typically go up to 75% LTV, with a 1.00 coverage floor, subject to lender guidelines.
- A lower projection means a smaller loan, more cash down, or a different property. It does not mean the file is dead.
- Clearing 1.00 is not the same as positive cash flow, because operating costs sit outside the ratio.
“Dropped projection” can mean three things: an income report that falls when refreshed, a lender reduction applied to the number, or an appraiser’s figure that lands below the model. The mechanics below cover all three.

What Is a Short-Term Rental DSCR Loan With No History?
A DSCR loan on a short-term rental qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. When the property has no hosting record, there is no trailing twelve months of bookings to document. The file needs a substitute for that history.
No statute or agency sets the substitute. These are business-purpose investor loans, reviewed differently from a standard owner-occupied mortgage. Each program writes its own rules. Because Lendmire arranges these loans through a wholesale network of DSCR lenders, the pattern across many guidelines is clearer than any single lender’s page. Most programs accept a projection on a purchase. Refinances lean on actual hosting history instead.
Lendmire’s complete DSCR loans guide covers the basic ratio. The short version: qualifying income divided by the full monthly payment, meaning principal, interest, taxes, insurance, and any association dues.
Key Terms Defined
Projection: An estimate of what a property would earn as a short-term rental, built from comparable listings rather than the property’s own bookings.
Haircut (expense factor): The reduction a lender applies to gross short-term income before running the ratio, because these properties carry heavier operating costs than long-term rentals.
Qualifying income: The reduced, lender-accepted income figure that goes into the numerator of the ratio.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the payment side of the ratio.
Form 1007: The appraiser’s long-term market rent schedule for a single-unit property. Form 1025 plays the same role for two-to-four-unit properties.
Comp set: The group of comparable listings a projection is built from.
How Does Underwriting Treat a Projection Step by Step?
Underwriting treats a projection as a claim to be tested, not a number to be accepted. The sequence runs the same way on most files.
1. Pick the evidence route. With no history, the choices are a market-data projection, an appraiser’s short-term rental analysis, or the long-term rent schedule. The program decides which are accepted.
2. Confirm the use is 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. A projection means nothing if the use is not permitted. Condo and HOA documents belong in the file at this stage.
3. Review the projection itself. The lender reads the report, checks that the property details match, and looks at how strong the comp set is.
4. Apply the reduction. The lender takes a haircut off gross revenue. The size varies by program, so ask for it in writing.
5. Run the ratio. The reduced income is divided by the full payment. The result is tested against the program floor.
6. Let the appraisal run in parallel. It supplies value plus a rent schedule. The ratio and the value together set the loan amount and leverage.
For short-term rentals in the network, purchase leverage typically tops out at 75% LTV, refinance runs around 70%, and the coverage floor is 1.00 on both purchases and refinances. Expect a credit score of 640 or higher and about 12 months of hosting experience as a general expectation. Those are guidelines, not promises, and each file is underwritten individually.
Where Does the Projection Come From?
Most projections come from a market-data tool. AirDNA’s Rentalizer documentation says the tool searches for comparable listings within a 10-mile radius. It picks them by proximity and by similar bedroom, bathroom, and guest-count setup. Then it takes a weighted average of their past performance.
The output is a 12-month estimate. AirDNA’s calculator page says it assumes the property is available all 365 days, refreshes its occupancy, rate, and revenue figures weekly, and rates comp-set strength as Low, Medium, or High.
That design explains most drops. The estimate is only as good as the comps and the property inputs.
| Evidence route | When it fits | What the lender reads |
|---|---|---|
| Market-data projection | Purchase, no history | Reduced annual estimate |
| Appraiser STR analysis | Purchase, program accepts it | Narrative income analysis |
| Form 1007 long-term rent | Fallback on a purchase | Traditional 12-month lease rent |
| Actual hosting history | Refinance, operating rental | Documented platform income |
Why Does a Projection Drop?
A projection drops when the comp set changes, the data refreshes, the property inputs get corrected, or a different evidence route comes in lower. Each one hits the coverage ratio the same way: less income over the same payment.
Comp set changes. AirDNA’s guide to analyzing a short-term rental notes that the nearest listings are rarely the truly comparable ones. In its sample, revenue potential among similarly sized properties ranged from roughly $29,500 to $55,000. Swap one comp set for another and the number moves a lot.
Weekly refresh. Because the data refreshes weekly, a report pulled before the offer can read differently by the time the lender orders one.
Wrong property details. A wrong bed, bath, or guest count pulls in the wrong comps.
Optimism in the model. VaultSTR, an analytics publisher, claims independent tests and operator reports put Rentalizer 15–30% away from actual performance, usually on the high side. That is one publisher’s claim, not a measured standard. It is a good reason to expect a lender to look hard at the raw figure.
A different evidence route. The appraiser’s rent figure can land below the model. HousingWire reports that Form 1007 was designed only to estimate long-term monthly rent, and that forcing short-term income into it often produces artificially low coverage ratios. An appraisal firm, Class Valuation, says competent appraisers report a labeled short-term income analysis as a narrative addendum instead, covering market-supported occupancy and seasonal pricing.
How Does a Lower Projection Move the Ratio?
A lower projection moves the ratio in direct proportion, because the payment stays put. Treat the table below as a sensitivity check on one property, not a quote. The scenarios are modeled assumptions, expressed as coverage ratios against a 1.00 floor.
| Scenario | Coverage vs. same payment | Against a 1.00 floor |
|---|---|---|
| Model projection, before reduction | About 1.40x | Clears |
| After lender reduction | About 1.15x | Clears |
| Corrected comps drop it further | About 1.00x | Borderline |
| Long-term rent schedule only | About 0.85x | Below |
The same house can clear on one evidence route and fail on another. A file that passes only on the optimistic number has a thin margin. Run the conservative case and the long-term rent case before going under contract.
Payment-side changes work the same way. Higher association dues, taxes, or insurance raise the denominator and can flip a pass to a fail with the projection unchanged.
What Can an Investor Do When the Projection Comes In Short?
An investor has five levers, and each has a cost. None of them fixes a property that cannot legally operate as a short-term rental.
1. Bring more cash to the purchase. A larger down payment lowers the payment and can lift the ratio. It does not erase leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage.
2. Correct the inputs and re-run. If bed, bath, or guest counts were wrong, fixing them changes the comp set. If the property is unusual, ask for a custom comp set.
3. Change the structure. Extended terms and interest-only periods are available through select lenders in the network, and they change the payment side. Ask what each does to the file.
4. Look at a sub-1.00 path. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. It is a separate path from the standard 1.00 floor, not a softer version of it, and it is subject to lender guidelines and credit approval.
5. Pick a different property. Sometimes the honest answer is a lower price, a different bedroom count, or a different submarket.
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 Does the General Rule Break?
The general rule is that a purchase can use a projection and a refinance uses history. Several edge cases bend it.
Partial or seasonal history. Investors with six or seven months of bookings often assume the lender will annualize them. Many lenders will not, because a strong season distorts the average. Treatment varies by program.
Thin comp data. RentalRecon says Rentalizer is most reliable in large, data-rich markets. In small or low-density markets the projection is a weaker document.
History and projection disagree. When actuals run below the model, expect the lender to lean on the documented number. That is program-specific, so confirm it before ordering an appraisal.
Conversion from a long-term rental. There is no short-term history, but there may be lease history. The route depends on the program.
Two-to-four-unit properties. These use Form 1025 rather than Form 1007 for the appraiser’s rent schedule.
Mismatched revenue definitions. AirDNA says its figures are host revenue net of platform fees. Other tools define revenue differently, for example with or without cleaning fees. The lender’s accepted report needs to match what the investor ran.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs, no matter how strong the projection looks.
What Does the Ratio Not Tell You?
The ratio compares rent to PITIA and nothing else. Clearing 1.00 does not mean the property makes money. Repairs, vacancy, management, cleaning, utilities, and capital expenses all sit outside the calculation.
Cash flow also arrives monthly while lenders average annually. Build a month-by-month table of rate, occupancy, and occupied days to see the slow-season troughs. A property can clear the test and still run negative for several months.
Reserves matter too. They vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA, and they are a separate test from coverage. Tax treatment varies; consult a qualified professional.
Questions to Ask Before Ordering the Appraisal
Ask these before spending money on an appraisal.
- Does the program accept a projection on a purchase with no history?
- Which report or tool does the lender accept?
- Does it order its own short-term rent analysis?
- What reduction is applied to gross income?
- Which figure wins if two disagree?
- What is the coverage floor for this property and leverage?
- What documents do condo or HOA rules require?
- What reserves apply at this loan size?

Frequently Asked Questions
Can I get a short-term rental DSCR loan with no booking history?
Often yes on a purchase, if the program accepts a projection or an appraiser’s short-term analysis. It is program-dependent. Expect about 12 months of hosting experience to be a general expectation, and expect a 640 or higher credit score, subject to lender guidelines.
Does a clean AirDNA report guarantee approval?
No. The lender reviews the projection and applies a reduction before running coverage. Comp selection and the tool’s own accuracy limits both matter, so the lender treats the report as a claim to test.
Will the appraisal prove my Airbnb income?
Not by itself. The standard rent schedule measures long-term rent. Some appraisers add a labeled short-term income analysis, and some programs accept it.
What happens if my projection drops after I’m under contract?
The ratio drops with it, since the payment does not change. The levers are more cash down, corrected inputs, a different structure, a sub-1.00 path through select lenders with adjusted terms, or a different property.
What leverage can I expect on a short-term rental purchase?
Typically up to 75% LTV on the strongest files, and around 70% on a short-term rental refinance or cash-out. Credit, reserves, and property review all affect the outcome.
