How To Get A Short-term Rental Rent Analysis With The Appraisal — The Quick Read: the standard rent form appraisers use for regular rentals, Form 1007, was built for monthly leases, not nightly bookings, and Fannie Mae has said outright that appraisers can’t just multiply a nightly rate by 30 to fake a monthly number. What actually happens on a short-term rental file is one of two things: the appraiser builds a separate narrative income analysis specific to nightly rentals, or the lender pulls a third-party data report instead of leaning on the appraisal form at all. Which path your file takes changes how much rent counts toward your DSCR ratio — and that changes your loan size.
Key Terms Defined
DSCR (debt service coverage ratio) — the rent divided by the full monthly payment (principal, interest, taxes, insurance, and any HOA dues). A ratio of 1.00 means the rent covers the payment exactly.

As of Sep 17, 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.

Form 1007 — the standard appraisal form used to document market rent on a single-unit rental property, built around comparable monthly leases.
ADR (average daily rate) — the average nightly price a short-term rental charges, before subtracting cleaning fees, platform commissions, or vacancy.
Rent analysis — the appraiser’s or underwriter’s documented estimate of what a property will earn, used to size the loan instead of the borrower’s personal income.
Comp set — the group of similar properties an appraiser or data platform uses to estimate what your property should earn.
Why the Standard Rent Form Doesn’t Fit a Nightly Rental
Form 1007 was never designed to price a nightly rental, and Fannie Mae’s own guidance says so directly. The form documents monthly market rent by comparing your property to nearby homes rented on a monthly lease, which works fine for a standard long-term rental and works badly for a beach house that rents by the weekend.
Per Fannie Mae’s Appraiser Update, the form “enables the appraiser to document the estimation of monthly market rent for the subject property when completing an appraisal on a single-family investment property.” Fannie Mae also flags the one shortcut every borrower has heard about and shouldn’t count on: taking a nightly rate and multiplying it by 30. That approach ignores furniture and fixture costs, cleaning and platform fees, vacancy between bookings, and the operating expenses a nightly rental carries that a normal lease doesn’t. Fannie Mae states plainly that Form 1007 “cannot be used to estimate the nightly fee” for a short-term rental — the form simply wasn’t built for that math, a point covered in more depth in Lendmire’s explainer on how STR appraisals and market rent actually work.
That leaves two real paths for getting an usable number.
Path One: The Narrative Rent Analysis Addendum
This is a document the appraiser produces. It’s separate from the standard rent schedule. It’s built specifically for nightly rental income. Instead of pulling comparable monthly leases, the appraiser pulls comparable nightly listings. This includes occupancy patterns, seasonal pricing swings, and a defensible set of comps from similar short-term rentals nearby.
This report typically sits alongside (or replaces) the standard rent schedule and gets labeled something like “Short-Term Rental Projected Income Analysis.” It documents the property’s realistic earning potential the way an experienced appraiser sees the market, rather than forcing a nightly rental into a monthly-lease box. Appraisers still can’t decide what counts as qualifying income — that call belongs to the lender’s underwriting team, not the person doing the property valuation. The appraiser documents the value and rent opinion; the lender decides how much of it counts toward your ratio.
Path Two: A Third-Party Data Platform Report
This route skips the appraisal form entirely and leans on a nightly-rental data platform — AirDNA’s Rentalizer tool is the one most often cited in lending circles. It estimates projected revenue, average daily rate, and occupancy for a specific address by pulling historical performance from comparable active listings nearby, and it even scores its own comp set strength as Low, Medium, or High so the underwriter knows how much confidence to put in the number.
This route exists because a straight lease-comparable number often badly understates what a nightly rental actually earns. A property that would show weak or negative coverage against a 12-month-lease comp can show solid, healthy cash flow once the file counts documented nightly income instead. That’s the entire reason lenders reach for a data-platform report on STR files — it captures income a standard appraisal form is structurally blind to.
Across the wholesale network Lendmire works with, short-term-rental income is typically counted at a discount to gross rent rather than at face value — most files see qualifying income run around 80% of gross STR revenue, and that income can come from either twelve months of documented operating history (on a refinance) or the appraisal’s short-term-rent analysis (on a purchase, where there’s no operating history yet to pull from). Programs like this are generally reserved for experienced investors — most lenders in the network want to see roughly a year of owning income property somewhere in the last three years before they’ll count nightly income this way. Coverage needs to clear roughly 1.00 on that discounted number for full leverage; this path isn’t available on no-ratio files.
What the Appraiser Actually Verifies (and What They Don’t)
The appraiser’s job is documenting comparable data, not deciding your qualifying income. That distinction trips up a lot of borrowers who assume a strong appraisal automatically means a strong DSCR number.
The appraiser gathers three or more genuinely comparable properties — same market, similar bedroom count, similar nightly-rental posture — and documents occupancy, seasonal pricing, and rate patterns. What the appraiser is explicitly barred from doing is treating personal property, furnishings, or the “business” of the rental as part of the real estate value. The report values the real property. It’s a separate underwriting step that decides how much of the documented income actually counts toward your loan.
This split matters because a file can have a strong appraisal and a disappointing DSCR number at the same time, or the reverse — a modest appraised value paired with strong documented nightly income that still clears coverage comfortably. Investors chasing a specific loan size should ask upfront which path the lender’s appraiser panel actually uses, since narrative addenda and data-platform reports don’t always land on the same number for the same property.
Reconciling Value and Income on the Same File
A DSCR appraisal is doing two jobs at once — setting the collateral value that drives your loan-to-value, and setting the rent number that drives your coverage ratio. On a standard rental those two numbers rarely fight each other. On a short-term rental, they can diverge more than borrowers expect, and the underwriter has to decide which conclusion actually controls the file.
Picture a coastal property with genuinely strong nightly bookings but a conservative appraised value because comparable sales in the area are thin. The rent side of the file might support a big loan on coverage alone, but the value side caps it. Or flip it: a beautifully valued property in a market where local nightly-rental comps are sparse or inconsistent, leaving the appraiser with a wide range and a cautious rent conclusion. Either way, the two conclusions get reconciled separately — they’re not the same number wearing two hats.
Across the STR files Lendmire’s network sees, the appraisal and the documented rent history are usually what makes a deal clear comfortably or stall — not the borrower’s credit profile. A borrower with clean credit and real reserves can still hit friction if the appraiser’s nightly-rent opinion lands conservative compared to actual bookings. This is exactly why matching the right documentation path to the right property matters before the file goes out.
Where This Breaks Down: Thin Markets and Tool Disagreement
Automated revenue tools disagree with each other constantly, and that disagreement is itself useful information. In a market where nightly rentals are new, rare, or geographically scattered, one platform’s projection and another’s can differ by a wide margin — not because either is wrong, but because there simply isn’t a deep, consistent comp set to draw from.
This shows up hardest in rural markets, newly-STR-legal areas, or unique properties without close comparables. When the comp set is thin, a single automated number stops being a reliable stand-in for what your specific property will earn — which is exactly why lenders lean on the appraiser’s judgment and documented history rather than trusting an address-in, number-out tool at face value.
Short-term rental rules can vary by city, county, HOA, and property type, so municipal permission to operate needs to be documented for the specific property being financed — never assumed just because a nearby property runs one.
Purchase vs. Refinance: Which Path You’re On a refinance, the file already has a track record — twelve months of documented operating history is the input, not a projection. That tends to be the more straightforward path, since the lender is reviewing actual booked income rather than an estimate.
On a purchase, there’s no operating history yet. So the appraisal’s short-term-rent analysis becomes the coverage figure instead. This is where the choice between a narrative addendum and a data platform matters most. There’s no trailing income to fall back on if the appraiser’s number comes in soft.
Borrowers weighing a bigger purchase can find the full leverage picture in Lendmire’s complete DSCR loans guide, which lays out how loan size steps down as leverage increases across the program.
A Rough Sizing Picture
Say an investor is buying a nightly-rental property. Say the appraisal’s short-term-rent analysis, after the standard discount to gross revenue, supports coverage clearing comfortably above 1.00. That’s the scenario most select lenders in Lendmire’s network want to see before extending full leverage on a short-term-rental file, generally up to a $2,000,000 loan amount on this specific program.
Coverage that lands closer to breakeven, or below 1.00, doesn’t automatically kill the deal — select programs in the network will still look at sub-1.00 and no-ratio files, though leverage and terms adjust to compensate, and none of that applies on the short-term-rental income path itself. Investors weighing that tradeoff should see Lendmire’s guide on how a rent analysis sets leverage on a short-term rental for how the numbers actually move.
DSCR loans are business-purpose loans for non-owner-occupied investment properties. Lenders review them differently than a standard owner-occupied mortgage. Qualification is based mainly on the property’s documented or projected rental income, not the borrower’s personal income documents, subject to lender guidelines.
Who This Fits — and Who It Doesn’t
This documentation path fits an investor who already has a real short-term-rental operating history, or a purchase in a market with a genuinely deep comp set of similar nightly listings. It does not fit well for a brand-new market with almost no comparable nightly rentals, or a borrower expecting an automated online estimate to be treated as gospel by an underwriter — those numbers are a starting point, not a final answer.
It also doesn’t fit anyone who assumes municipal approval is automatic. Local permission to run a short-term rental has to be documented property by property. That documentation sits alongside the rent analysis in the underwriting file — it isn’t separate from it.
This isn’t legal or tax advice. Program details can change. Investors should confirm current guidelines with a licensed professional. Where relevant, they should also consult a qualified attorney or CPA about their own situation before using any of this to make a financing decision.

Frequently Asked Questions
Can I just use an AirDNA estimate instead of getting an appraisal?
Not usually on its own. Most lenders still want a property appraisal to establish value, and the AirDNA-style report supports the income side of the file rather than replacing the appraisal entirely. The two documents typically work together, not as substitutes for each other.
Why did my appraiser’s rent number come in lower than what my property actually earns on Airbnb? Appraisers pulling comparable monthly leases (rather than a nightly-rental-specific analysis) will almost always land below your actual nightly income, since that comp set wasn’t built to capture nightly pricing or seasonal swings. Ask whether the lender’s panel can produce a narrative short-term-rental addendum instead of the standard lease-comparable schedule.
Does a strong Airbnb track record guarantee a bigger loan?
No — documented history helps, but it’s not a guarantee of a specific loan size or approval. The lender still weighs the appraised value, the discount applied to gross rent, credit, reserves, and overall underwriting before sizing the loan, all subject to program guidelines.
What if my market doesn’t have enough short-term-rental comps?
Thin comp markets are a real limitation — automated tools can disagree sharply with each other when comp density is low, and appraisers may land on a more conservative number as a result. This is one of the harder scenarios in STR financing and often points toward a narrative appraisal approach over a pure data-platform report.
Is short-term-rental income treated the same as long-term rental income on a DSCR loan?
No. Most programs in Lendmire’s network apply a discount to gross short-term-rental revenue before counting it toward coverage, and they typically require documented experience owning income property before extending that specific path — it also isn’t available on no-ratio programs.
Are you buying or refinancing a short-term rental? Do you want to see how the rent analysis actually shapes your loan size? Lendmire can help you compare DSCR loan options.
