A long-term rental DSCR loan qualifies a property against a lease. A short-term rental doesn't have one -- it has a booking calendar. STR DSCR loans exist to bridge that gap, letting investors finance an Airbnb or vacation rental against its projected or actual nightly income instead of a 12-month lease. The underwriting is genuinely different, and getting it wrong is the fastest way to have a deal fall apart at the term sheet stage.
How STR Income Actually Gets Underwritten
Lenders qualify STR income one of two ways: actual performance, using 12 months of host platform statements (Airbnb, VRBO) showing real booking revenue, or projected performance, using a third-party market rent report -- typically from AirDNA -- that estimates what a comparable property in that market would generate. When a lender relies on a projection rather than a track record, it's standard practice to apply a haircut, discounting the projected gross revenue to somewhere around 75%–80% before dividing by 12 to get the monthly income figure used in the DSCR calculation.
STR DSCR income, projection-based: AirDNA projected annual gross revenue × ~75–80% haircut ÷ 12 = qualifying monthly income used in the DSCR formula. A property with 12+ months of actual host statements can often qualify off real numbers instead.
What Counts as a Good STR DSCR Right Now
Because short-term rental income carries more seasonality and platform risk than a signed lease, lenders generally want to see a stronger cushion than they would on a long-term rental file. Strong-credit borrowers with well-documented performance in established markets have been able to reach DSCRs in the 1.25–1.65 range in top-performing STR markets, compared to the 1.0–1.25 range that's typical on a standard long-term-lease DSCR loan. Pricing for a clean STR DSCR file -- 720+ credit, roughly 1.15 DSCR, 75% LTV, seasoned 12+ month host history -- has run in a 6.625%–7.500% range through mid-2026 for well-seasoned properties in lower-regulation markets, with weaker files or heavier regulatory exposure pricing higher.
Why STR Growth Slowing Down Is Actually Good News for Buyers
AirDNA's 2026 Short-Term Rental Outlook projects U.S. available STR listing growth of just 4.6% for the year, a fraction of the roughly 20% annual expansion the industry saw at its 2021–2022 peak. Slower new-supply growth means less new competition flooding markets that are already established, which is part of why AirDNA frames 2026 as a window with real opportunity for investors entering STR markets that were oversaturated a few years ago.
Where Regulation Risk Gets Priced In
Unlike a long-term rental, an STR's legality can change with a single city council vote -- a permit cap, an owner-occupancy requirement, or an outright ban. Lenders account for this by looking at the specific jurisdiction's STR ordinance status, not just the property's numbers: a market with stable, established STR permitting supports higher leverage and better pricing than one with active regulatory proposals pending. Nashville, for example, has remained a top-tier STR market in 2026 in part because its regulatory framework is comparatively settled, while markets facing new restriction proposals see lenders tighten leverage or price in the added risk.
| Income basis | LTR DSCR: signed lease or market rent comp | STR DSCR: AirDNA projection (haircut applied) or 12 months of actual host statements |
|---|---|
| Typical qualifying DSCR | LTR DSCR: 1.0–1.25 | STR DSCR: 1.25–1.65 in top-performing markets |
| Key added risk factor | LTR DSCR: vacancy | STR DSCR: seasonality, platform dependency, and local regulation |
Before You Apply
- Pull an AirDNA market report for the specific property, not the metro average -- STR revenue varies block to block near key attractions
- If you already operate the property or a comparable one, gather 12 months of platform statements; actual performance underwrites more favorably than a projection in most cases
- Confirm the property's STR legality and any permit or registration requirements in that specific city before you assume the numbers will qualify
- Model your DSCR at the haircut-adjusted income, not the raw projected revenue, so you're not surprised by the number your lender actually uses
The Bottom Line
STR DSCR loans open up financing for a property type long-term-lease underwriting was never built for, but the tradeoff is a lender that discounts your income more conservatively and prices in regulatory risk your neighbor's long-term rental doesn't carry. Come in with real booking data or a defensible market report, and know your jurisdiction's STR rules cold before you make an offer.
