The Quick Read: A lender can underwrite a converting owner on the rent the property already earns under a lease, or on a third-party income projection for short-term hosting, and the right path depends on the program’s accepted income evidence, the appraisal rent figure, and whether the owner can wait for hosting history. Lease history is the stronger evidence, while a projection is the more realistic picture of what the converted property may earn.
- Lease history proves tenant payment and real expenses, but it measures twelve-month tenancy, not nightly-rate income.
- A projection can capture the higher short-term income, but only some programs accept one, and lenders usually discount it.
- Short-term-rental purchase leverage tops out at 75% LTV and refinance or cash-out at about 70%, with a 640+ credit score expected.
- Clearing 1.00 coverage is not the same as positive cash flow, because repairs, vacancy, management and utilities sit outside the ratio.
The Honest Answer: Who Each Path Is Really For
Lease history fits the owner whose current rent already covers the full monthly obligation with room to spare. That owner can refinance or hold on stable evidence and let hosting history build on the side. A projection fits the owner whose lease income barely covers the payment, or does not cover it, but who has a defensible reason to expect much higher nightly revenue. That owner needs a program that will actually read the projection, and those are fewer than most investors assume.
Neither path is better in the abstract. Lease evidence is conservative and easy to document. A projection is forward-looking and easier to overstate, which is why lenders handle it with more caution.
Across the wholesale network of DSCR lenders that Lendmire places files with, the income evidence a program accepts can differ from one lender to the next on a conversion file. Some programs lean on appraiser long-term rent. Some will take trailing short-term-rental statements. A smaller group will consider a market projection. Asking which of those a program accepts, before ordering anything, helps avoid wasted effort. The complete DSCR loans guide covers the baseline mechanics if you want the full picture first.
Side-by-Side
| Factor | Lease History | Projection |
|---|---|---|
| Review basis | Rent under lease or appraiser rent schedule | Third-party STR income report plus appraisal |
| Documentation | Signed lease, rent ledger, appraisal rent schedule | Projection report, STR appraisal addendum |
| Property types | 1–4 unit rentals; manufactured, log, barndominium not offered | Same; STR use must be legal at the address |
| Entity vesting | LLC vesting common, per program terms | LLC vesting common, per program terms |
| Hosting history needed | None on the lease path | About 12 months of landlord or host experience typical |
| Reserves | Commonly around 6 months of PITIA | Commonly around 6 months of PITIA; varies |
| Main risk | Understates short-term income | Overstates income; fewer programs accept it |
The table reflects how select lenders in the network commonly treat each path. Reserves, leverage and documentation flex by lender, loan size and transaction type, and every file is underwritten individually.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rental income divided by the monthly principal, interest, taxes, insurance and any HOA dues (PITIA).
Lease history: the record of signed leases, rent payments and expenses an owner already holds from tenancy.
Projection: an estimate of future short-term income built from comparable listings, seasonality and occupancy assumptions.
Form 1007: the appraiser’s single-family rent schedule, which estimates market rent on a traditional lease.
Form 1025: the small residential income property report used for two-to-four-unit properties.
ADR and occupancy: average daily rate and the share of nights booked, the two inputs that drive short-term revenue.
Narrative addendum: a written appraiser analysis attached to the report to support short-term income that the rent schedule cannot capture.
What Does Lease History Actually Prove?
Lease history proves that a tenant paid, that the property held occupancy, and what the property costs to run. It is evidence an underwriter can verify from documents rather than assumptions, and that is its real strength. A multi-year rent ledger also shows an owner who understands the asset, which matters because short-term-rental programs usually expect about 12 months of landlord or host experience. For a converting owner, years of landlord experience may support that expectation, subject to lender guidelines.
What lease history cannot prove is short-term income. A lease reflects a twelve-month tenancy at a negotiated rent. It says nothing about nightly demand, seasonality or how guests will respond to the property.
There is also a wrinkle on the appraisal side. Some DSCR lenders use only the appraisal figure, while others allow a variance when a current lease exists. A tenant’s lease is therefore not automatically the qualifying income, and the owner should ask which number governs before assuming the lease will carry the file.
For the appraisal itself, Fannie Mae’s forms index names the Form 1007 rent schedule for one-unit properties and Form 1025 for two-to-four units. Those forms are cited here only to name the documents, since they do not set the rules for DSCR loans.
What Is a Projection, and Why Do Lenders Handle It Carefully?
A projection estimates what the property could earn as a short-term rental using comparable listings, seasonality, ADR and occupancy. Data vendors produce these reports, and Rabbu describes the DSCR approach as underwriting on the property’s projected income rather than on traditional personal-income documentation. That is vendor commentary, but it matches how the loans are structured: the property’s rental income covering the payment, subject to lender guidelines.
The catch is acceptance. Only a minority of programs will use a projection to qualify a file, and those that do typically apply a discount to projected revenue before dividing by PITIA. The size of that discount varies by program, so the number a projection report prints is rarely the number that goes into the ratio.
The appraisal matters just as much. HousingWire reports that using Form 1007 for short-term income introduces compliance risk and often distorts DSCR calculations, producing artificially low ratios. The same piece notes that narrative addenda will remain essential even as the legacy forms are retired under UAD 3.6. Class Valuation, an appraisal-industry firm, makes the same point and says competent short-term-rental appraisers document income in a labeled projected-income analysis rather than on the rent schedule.
One more correction belongs here. Multiplying a nightly rate by thirty does not produce a valid monthly rent. Fannie Mae’s appraiser update, hosted by the Nevada Real Estate Division, says Form 1007 relies on monthly-lease comparables and was not designed for short-term income.
When Lease History Is the Better Fit
Lease history is the better fit when the existing rent already clears the coverage test on its own. An owner whose lease income lands at roughly 1.2x or better on the full obligation has a file that does not depend on anyone accepting a projection. That owner can refinance on documented rent, keep the tenant through the end of the lease, and treat the Airbnb conversion as an upside rather than a qualification requirement.
It also fits the owner who cannot afford a gap. Converting means ending a tenancy, furnishing, and building a booking record, and the property earns less during that stretch. An owner who needs the loan to work before any of that happens is better off refinancing while the lease is still in force.
Leverage is part of the calculation as well. On a standard long-term rental, cash-out refinances tend to top out around 75% LTV across most of the network, with about 6 months of seasoning the common expectation. Short-term-rental collateral is more conservative, at about 70% for refinance and cash-out. An owner who needs maximum proceeds may do better closing the transaction on long-term collateral first. That choice is worth weighing deliberately, since income evidence and collateral classification interact.
The tradeoff is that lease-based qualification may understate what the property can earn. If the rent is thin, coverage may come in below 1.00. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted, but that path trades away cash-out room and should be a deliberate choice, not a default.
When a Projection Is the Better Fit
A projection is the better fit when the lease rent leaves coverage thin and the short-term market is genuinely strong. If the gap between appraiser long-term rent and credible short-term revenue is wide, a rent-schedule-only file can fail the test even though the converted property would carry its debt comfortably. In that situation the projection, paired with a proper short-term-rental appraisal addendum, is the document that tells the real story.
It also fits the owner who can wait. Someone who is willing to season hosting history can start on the projection path and later move to actual history, which is stronger evidence than any forecast. On short-term-rental programs, purchases generally run up to 75% LTV and refinances about 70%, a 640+ score is expected, and the coverage floor is 1.00 on both purchases and refinances. Those are the program ranges that apply once the property is treated as a short-term rental.
Two cautions apply. First, a projection is only as defensible as its inputs. A report that assumes peak-season occupancy all year will not survive underwriting. Second, the projection does not resolve legality. If the address does not allow short-term use, no income figure will rescue the file.
A genuine toss-up exists when the short-term market is moderate. The projection may beat the lease number by a modest margin, but a discount applied to it can erase that margin. In a weak short-term market, the long-term fallback may be the figure that actually clears, so run both before choosing.
How Do the Two Paths Compare on a Real Conversion?
Consider three modeled scenarios, with the coverage ratios used as assumptions rather than market data.
Picture an owner whose lease income covers the full monthly obligation at around 1.3x. The lease path carries the file, a projection adds nothing the lender needs, and the owner can convert on their own schedule.
Say a second owner’s lease lands near 1.0x and the projection suggests 1.5x before any discount. After the lender’s discount the projection might sit closer to 1.2x. That owner gains real coverage by taking the projection path, provided the program accepts one and the owner can document the assumptions.
Run the numbers on a third owner whose lease sits at 0.9x. The lease path lands below 1.00, where select lenders in the network may review the file with leverage and terms adjusted. The projection path may do better on paper, but only if the market supports it. If neither path clears at the neighborhoods under consideration, that signals a pricing or submarket problem, not a loan-type problem.
In none of these cases does clearing 1.00 mean the property cash flows. DSCR compares rent to PITIA only, so management, repairs, vacancy, utilities and capital reserves remain outside the ratio. An owner moving from a tenant to guests absorbs several costs the tenant used to cover, and those belong in the conversion decision even though the lender never sees them.
Documents to Keep and Documents to Start Generating
Keep the lease-era record intact: signed leases, the rent ledger, expense records, and proof of the lease’s end or termination. These show the baseline and support the landlord-experience expectation.
Start building the hosting record from the first booking: platform payout statements, bank deposits, and any manager reports. Short-term-rental files also commonly ask for any required permit or license, insurance suited to short-term use, and entity documents. Vesting in an LLC is common and generally available, subject to lender program eligibility. Lendmire’s article on how STR1007 compares with booking history for an investor converting to long-term rental covers the reverse-direction version of this documentation question.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Common Mistakes
Owners often order a rent-schedule-only appraisal on a property they plan to run as a short-term rental, then discover the coverage ratio is artificially low. Asking up front for a short-term-rental narrative addendum avoids that outcome.
Another mistake is assuming every program takes a projection. Confirm the accepted income evidence before paying for a report.
A third is treating a projection as a promise. It is an estimate, and lenders will discount it.
A fourth is ignoring the gap. Between the last tenant and the first bookings, the property carries its costs without full income, so reserves matter. Reserves vary by lender, leverage, loan size and transaction type, and are commonly around 6 months of PITIA.
The Balanced Verdict
Lease history wins on certainty, and a projection wins on upside. If the existing rent clears coverage with room to spare, the lease path is usually the lower-friction route, and the conversion can proceed without asking a lender to believe a forecast. If the lease falls short and the short-term market is strong, a projection paired with a proper appraisal addendum is the stronger argument, with the caveat that fewer programs accept it and a discount will apply.
The flip point is the coverage number. Where lease income already clears the program’s floor, lease history is hard to beat. Where it does not, the question becomes whether the projection is credible enough to survive a discount, and whether the owner can wait for actual hosting history to replace it.
Frequently Asked Questions
Can a lender use my existing lease to review a loan on a property I plan to run on Airbnb?
It depends on the program. Some programs underwrite on lease or appraiser long-term rent, while others require short-term-rental history or a projection.
Do I need booking history before a short-term-rental program will review my file?
Not always, but programs typically expect about 12 months of landlord or host experience, and an owner with years of lease records may satisfy that through landlord experience, subject to lender guidelines. Actual hosting history is the strongest evidence, and a projection is the fallback when history does not yet exist.
Why does the appraisal rent often come in below what I expect to earn on Airbnb?
The Form 1007 rent schedule estimates traditional twelve-month rent and cannot capture nightly-rate income. That is why a short-term-rental narrative addendum is requested, so the appraiser documents projected income separately instead of forcing it into the wrong form.
Does clearing 1.00 coverage mean the converted property will cash flow?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, cleaning and capital costs sit outside the calculation, so an owner should model net operating income separately.
What leverage can I expect if I convert and refinance?
On short-term-rental collateral, refinance runs around 70% LTV and cash-out about 70%, while a standard long-term rental cash-out tops out around 75%. A 640+ credit score is typically expected for short-term-rental programs, and most programs generally prefer closer to 660 on standard files. Every file is underwritten individually.
