Short-Term Rental Loans in Idaho: Financing the Airbnb, Honestly
Program and regulatory figures verified July 24, 2026. Details change; confirm your scenario with us.
The lending question on an Idaho short-term rental is simpler than in most states: can the revenue be documented? Idaho's 2026 preemption law took the permit uncertainty largely off the table, so the file comes down to income and the DSCR structure.
Can I finance an Airbnb with a DSCR loan? How is short-term rental income counted?
Yes, and there are three lanes, in order of underwriting strength:
- Operating property with 12 months of platform history: trailing Airbnb or Vrbo statements support the ratio directly. The cleanest file, and the reason an established, well-booked STR is worth a premium at purchase.
- No history, long-term-rent fallback: the appraiser's Form 1007 market rent qualifies the loan as if it were a long-term rental. If the deal pencils on that rent, the STR upside is margin, not a lending assumption. This is the structure we recommend most often.
- No history, STR projection: some programs accept a market-data projection with a haircut, commonly 20–25% off the projected revenue (a few use 70–80% of projection). More down and more reserves usually ride along.
Program specifics vary, and this is where a direct lender who writes these weekly earns the fee: we tell you which lane your property fits before you're under contract. Ratio mechanics: the Idaho DSCR guide.
Why Idaho is one of the easier STR states to finance
In most states, the first question on a short-term-rental loan is whether the city will let the property operate at all. Idaho took that risk down hard in 2026. HB 583 bars every city and county from requiring an STR license, permit, or registration, so the deal doesn't hinge on a permit lottery, a cap that's already full, or a council vote pending next month. That doesn't make every property a good deal, but it removes the single biggest reason STR loans fall apart elsewhere. The legal background is in Idaho STR law under HB 583.
Where the Idaho STR revenue actually is
The resort towns lead, and they diverge. Sun Valley averaged about $48,800 in host revenue per listing over the trailing year to May 2026 on a $635 average daily rate; McCall averaged roughly $32,092 at a $356 rate across 533 listings. North Idaho's lake season and the Teton Valley near Driggs add more demand. We underwrite the specific property's documented performance, not the market headline, and on a no-history property we anchor to Form 1007 market rent so the deal survives a soft season. Resort economics in depth: Sun Valley and McCall.
Taxes and your loan
Qualifying revenue is gross rent before lodging taxes, so Idaho's 6% state sales tax and the resort local-option taxes (Sun Valley 9% combined, McCall 7% combined) don't shrink the ratio. They belong in your operating model, and under the 2026 framework the platforms register with the Idaho State Tax Commission and remit them on bookings, which simplifies your bookkeeping.

Frequently asked questions
Can I finance an Airbnb with a DSCR loan in Idaho?
Yes. An operating STR with 12 months of platform history qualifies on its trailing revenue. A property without history qualifies on the appraiser's market rent, or on a revenue projection with a haircut (commonly 20–25%) under some programs. Down payment and reserves scale with how aggressive the income documentation is.
Do I need a permit before financing an Idaho short-term rental?
No city or county STR operating license exists to get: HB 583 (effective July 1, 2026) bars Idaho cities from requiring one. That removes the permit contingency that complicates STR loans in other states. We still confirm any baseline safety requirements and the resort tax posture, and on an uncertain-income property we anchor the loan to long-term market rent.
How much short-term rental revenue do Idaho properties make?
It varies widely by market. Sun Valley averaged about $48,800 per listing and McCall about $32,092 over the trailing year to May 2026 (AirDNA and AirROI). We underwrite the specific property's documented performance rather than a market average, and use Form 1007 market rent as the conservative anchor on a no-history purchase.
