What Counts As Short Term Rental Income For A Lender — The Quick Read: Most DSCR programs qualify a short-term rental using the lower of two numbers — trailing or projected platform revenue (Airbnb, VRBO, or a comparable booking history) versus the appraiser’s long-term market-rent opinion — then apply a haircut to the platform figure before it reaches the debt-coverage calculation. Some lenders skip STR income entirely and underwrite the property as a long-term rental instead. Which path a file takes depends heavily on the program, the operating history, and how the appraisal is documented.
There’s no single rulebook here. Short-term rental income isn’t governed by a federal underwriting standard the way owner-occupied mortgages are — DSCR loans are business-purpose, non-owner-occupied investment loans, and they’re reviewed differently from a standard owner-occupied mortgage. That gap is exactly why two lenders can look at the identical Airbnb listing and land on two different qualifying numbers.

Key Terms Defined
Trailing twelve-month (T12) income — the actual gross booking revenue a property generated over the prior 12 months, pulled from platform statements, a property manager’s ledger, or the owner’s bank deposits.
Form 1007 / Form 1025 — appraisal exhibits (single-family and 2-4 unit, respectively) that non-QM programs borrow as a naming convention for the rent opinion. They report a monthly lease-equivalent rent, not a nightly-rate conversion.
Haircut — the percentage discount a lender applies to raw platform or projected revenue before it counts toward debt coverage, meant to absorb vacancy, cleaning fees, platform commissions, and seasonality.
DSCR (debt service coverage ratio) — rent divided by the full monthly housing obligation (principal, interest, taxes, insurance, and HOA dues where applicable). It measures whether the property’s income covers its own payment — it is not the same thing as positive cash flow, since repairs, management, utilities, and reserves for capital expenses sit outside the ratio entirely.
Rentalizer-style projection — a third-party market-data estimate (AirDNA is the most common example) used when a property has no operating history yet, built from comparable listings within a defined radius rather than the subject property’s own bookings.
Two Paths: How Conventional and DSCR Loans Treat STR Income Differently
The core split is documentation source, not just math: conventional financing runs on the borrower’s personal income and tax-return history, while DSCR financing runs on the property’s own rental income. That distinction decides which STR files can qualify at all.
Conventional/agency underwriting generally wants two years of Schedule E history showing the STR activity, and it leans on the same Form 1007/1025 rent schedule used for long-term leases — a form appraisers are specifically instructed not to build by taking a nightly rate and multiplying by 30, because that method ignores furniture, fixtures, services, vacancy, and business expenses, according to Fannie Mae’s own appraiser guidance. A new-acquisition STR with no tax-return history often can’t clear that bar at all under a DTI-based program.
DSCR/non-QM lending sidesteps the tax-return requirement and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Trade coverage of non-QM mechanics describes the mainstream approach directly: lenders take the lower of the trailing 12-month short-term rental average and the comparable market rent from Form 1007 or 1025, per Scotsman Guide. That “lower of” structure is the closest thing the industry has to a shared standard, though individual programs still vary in how strictly they apply it.
| Factor | Conventional / Agency | DSCR / Non-QM |
|---|---|---|
| Income basis | Borrower traditional personal-income documentation, Schedule E | Property’s own rental income |
| STR history needed | Typically 2 years, tax-reported | Varies — 12 months common, some accept none |
| No-history purchases | Generally cannot use STR income | Market-data projections often accepted |
| Rent documentation | Form 1007/1025 lease-equivalent | Form 1007/1025 plus platform statements |
| Underwriter’s fallback | Long-term rent only | Lower of platform income vs. long-term rent |
Not every DSCR lender even quotes short-term rental income. Because STR is treated as a volatile, regulation-exposed asset class, Scotsman Guide reports that a meaningful share of the DSCR lender pool won’t count Airbnb-style rent at all and will underwrite the property as a long-term rental by default — which usually produces a lower coverage figure than the property’s actual nightly-rate earning potential. Program selection, in other words, is half the battle.
How Lenders Document STR Income, Case by Case
Documentation splits into three distinct scenarios, and mixing them up is the fastest way to slow a file down.
Existing STR with 12+ months of operating history. This is the cleanest case. A lender wants the platform’s own account statements (Airbnb/VRBO host earnings summary), a property manager’s income statement, or 12 months of the owner’s bank deposits tying back to the booking activity. The appraiser still produces the long-term rent opinion for comparison, and the lower-of-two-sources rule typically applies.
New purchase with no operating history. Here the file leans on third-party market data. AirDNA’s Rentalizer tool, the most commonly cited example, builds its projection by pulling comparable listings within roughly a 10-mile radius, matched on bedroom count, bathroom count, and guest capacity, then weighting their historical performance for seasonality and demand, according to AirDNA’s own methodology documentation. Some programs accept this on purchases only; others want it paired with an appraiser’s independent STR income opinion.
Hybrid or mixed-use buildings. A duplex or fourplex running one unit on a nightly platform and another on an annual lease gets underwritten on a blended rent roll — the STR unit follows the STR documentation path above, and the leased unit follows standard long-term rent verification. Larger STR-heavy buildings (five to eight units, say) sit in an awkward gap: too big for most 1-4 unit residential DSCR boxes, too small for agency multifamily programs, and the STR income narrows the available lender pool further.
How the coverage figure Actually Gets Built
The raw number on a host’s dashboard is never the number a lender uses. Programs discount platform income before it ever touches the debt-coverage formula, and the discount range varies by lender.
The typical pattern: take trailing or projected gross platform revenue, then apply a haircut commonly in the 20% to 30% range to absorb vacancy, cleaning fees, platform commissions, and seasonal swings. More conservative underwriters go further — independent review of AirDNA’s Rentalizer tool found its projections can run 15% to 30% optimistic compared to actual performance, particularly in thinner markets where a single unusual comp can skew the estimate. That’s the practical reason some programs discount projected income down to roughly 60% to 75% of the raw AirDNA figure rather than the more common 70-80% range applied to trailing platform statements.
Once the discounted platform figure exists, it gets compared against the appraiser’s long-term market-rent opinion, and the lower of the two typically becomes the qualifying monthly income used in the DSCR formula. Run the logic on a hypothetical: assume a coastal vacation property shows strong seasonal bookings on its platform statements, but the appraiser’s long-term rent comparable comes in well under the discounted STR figure. In that case, most programs would default to the lower long-term-rent number for qualification purposes — a structurally conservative approach that protects against an optimistic platform projection carrying more weight than it should.
DSCR files in STR-heavy markets tend to follow a consistent pattern across the wholesale network: the properties that clear underwriting cleanly are almost always the ones where the borrower supplies both the platform’s trailing income statement and a market-data report up front, rather than waiting for the underwriter to ask for the second data point. Files that show up with only one source of income evidence get stuck in a documentation loop far more often than files that anticipate the lower-of comparison from the start.
Investors weighing whether to lean on the STR number or the long-term equivalent can compare both approaches directly through Lendmire’s breakdown of short-term rental versus long-term rental cash flow for lenders.
What Can Zero Out STR Income Regardless of Revenue?
Strong revenue means nothing if the unit can’t legally operate as a short-term rental. Local ordinances, licensing requirements, and HOA minimum-stay rules sit outside the income calculation entirely — but any one of them can block a lender from counting the income at all, no matter how strong the trailing platform statements look.
Three gates matter before income even reaches the DSCR formula:
- Zoning and permitting. A city or county STR permit that was valid when the seller operated the property doesn’t automatically transfer, and permitted use at origination isn’t guaranteed to stay permitted.
- HOA and condo restrictions. Minimum-stay requirements or outright STR bans in an HOA’s governing documents can override everything else, even in a jurisdiction with no citywide restriction.
- STR-appropriate insurance. A standard landlord policy generally doesn’t cover nightly-rental use; the coverage type has to match the actual use of the property.
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. It’s worth reading Lendmire’s overview of what a short-term rental loan actually requires before assuming a property’s nightly-rate potential will carry the file.
Common Misconceptions About STR Income
“My Airbnb makes strong money, so that’s my qualifying income.” Not quite. The qualifying figure is a haircut-adjusted, often lower-of-two-sources number, not gross platform revenue.
“Appraisers can just take my nightly rate and multiply it by 30.” Fannie Mae’s guidance directly rejects this method for the 1007 rent schedule, since it ignores furniture, services, vacancy, and business expenses baked into nightly pricing.
“If Fannie Mae publishes STR appraisal guidance, DSCR loans must follow Fannie Mae’s rules.” DSCR loans aren’t sold to Fannie Mae or Freddie Mac. The 1007/1025 forms get borrowed purely as a naming convention for the rent exhibit — each non-QM program sets its own STR income policy independently of the agency selling guide.
“AirDNA numbers are a precise projection.” They’re presented as a single figure, which reads as more precise than the underlying methodology actually supports — comparable-based estimates carry a real margin of error, wider in thinner markets.
What This Means for Leverage, Credit, and Reserves
Program mechanics on STR-specific DSCR loans run tighter than a standard long-term-rental file, and the numbers matter more here because the income calculation itself carries more variability. Across the wholesale network, STR purchases typically top out around 75% loan-to-value, with cash-out refinances generally capped closer to 70% LTV. Most STR programs want a credit score around 700 and roughly 12 months of landlord or host experience — a stricter bar than the standard long-term-rental DSCR box, which reflects the added income-verification risk discussed above.
DSCR floors on STR purchases and refinances both typically sit around 1.00 as a baseline, though that’s a program-level starting point, not a universal rule — stronger coverage generally opens better leverage and pricing tiers. When a property’s discounted qualifying income lands below that 1.00 threshold, sub-1.00 coverage programs are still available through select lenders in the network, though leverage and terms adjust to compensate. Loan sizes on these programs commonly run up to $3,000,000, and above roughly $2,500,000 the network generally holds to 30-year fixed structures rather than adjustable terms; smaller balances often route through a narrower set of lenders within the network. Reserve requirements vary by lender, leverage, and loan size — a conservative rate-and-term refinance under $1,500,000 can occasionally see reserves waived, while loans above that threshold typically step up to roughly 9 months of PITIA in reserve.
Investors weighing whether to structure around STR income or pivot to a long-term-lease DSCR file at all should start with Lendmire’s complete DSCR loans guide, which walks through how coverage, leverage, and credit interact across property types — and for equity already built up in an operating short-term rental, refinancing options built specifically for STR investors are worth comparing against a standard cash-out structure before locking in a program.
If a file is close on paper but the property’s income relies on projected rather than trailing data, that’s exactly the kind of scenario worth reviewing with a broker before submitting to a single lender. Lendmire, NMLS# 2371349, arranges DSCR financing through select lenders in its wholesale network spanning 40 markets, including Washington, D.C., and can help compare how different programs would treat the same property’s rental income before a borrower commits to one lender’s methodology. Investors can request a comparison directly through Lendmire’s quote request page or by calling 828-256-2183.
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.
Loan approval is never guaranteed, and nothing here is a commitment to lend. Every scenario described here is subject to lender approval and to borrower, property, and program guidelines, all of which are set independently by individual lenders in the network and can change.

Frequently Asked Questions
Does a lender use my Airbnb’s actual monthly income to qualify me?
Not the raw number. Most STR DSCR programs apply a haircut — commonly in the 20% to 30% range — to trailing or projected platform revenue, then compare that discounted figure against the appraiser’s long-term market-rent opinion and use whichever is lower.
What if I just bought the property and don’t have 12 months of rental history?
Some programs accept third-party market-data projections, like an AirDNA-style comparable estimate, in place of trailing platform statements on a purchase. Not every lender does this, so program selection matters more for a no-history purchase than for a refinance with an operating track record.
Can a lender still count STR income if the DSCR comes in below 1.00 on that basis?
Coverage below 1.00 is available through select lenders in the network, though leverage and terms get adjusted to compensate for the weaker ratio. Whether a specific file qualifies depends on the property, the borrower’s credit profile, and the individual lender’s overlays.
Does a short-term rental need a different credit score than a long-term rental DSCR loan?
Generally yes — STR-specific DSCR programs typically want a credit score around 700, higher than what many long-term-rental DSCR programs require, reflecting the added variability in how STR income gets verified.
What happens if my city or HOA restricts short-term rentals after I close?
That risk sits outside the income calculation and can affect the property’s ability to operate as an STR going forward. Short-term rental rules can vary by city, county, HOA, and property type, so confirming local rules before relying on projected rental income is worth doing at the front end of the file, not after closing.
Investors focused on short-term rentals can review DSCR loans for Airbnb and short-term rentals.
