By Patrick Penner, NMLS #459913 · Idaho DSCR Specialist| Published July 1, 2025 Updated August 4, 2026A short-term rental DSCR loan qualifies the property on projected or documented Airbnb/VRBO income rather than your personal income. Only STR-friendly lenders count nightly-rental revenue — using AirDNA data or 12 months of booking history — usually with a 25–30% income haircut and a minimum DSCR near 1.10 to 1.25.
Short-term rentals can generate significantly more income than long-term rentals in the right markets — and that income potential is exactly why STR DSCR financing requires more nuance. Lenders who understand STR properties are not the same lenders who handle standard rental loans. STR demand isn't hypothetical: the U.S. Census Bureau's 2023 American Community Survey counts roughly 45 million renter-occupied housing units nationally, and short-term platforms compete for a slice of that housing stock in high-demand recreation markets.
How Is STR Income Documented for a DSCR Loan?
This is the central question. Long-term DSCR loans use a lease or a 1007 appraisal to establish rent. STR loans don't have a lease — they have booking history and projected occupancy. Lenders handle this in several ways:
- 12-Month Operating History: The most conservative approach. Lenders who require this want to see actual Airbnb/VRBO revenue statements showing what the property earned over the prior year. Best for stabilized STR properties with a track record.
- AirDNA or STR Data Services: Some lenders accept projected income from third-party data providers like AirDNA, which aggregates nightly rates and occupancy by market. This opens the door for new acquisitions without operating history.
- 1007 with STR Comparable Rents: A small number of lenders allow the appraiser to use STR-comparable data in the rent schedule. This is the most flexible — and rarest — approach.
Many DSCR lenders require a long-term lease and won't accept STR income at all. If you apply to one of these lenders with an Airbnb property, you either get declined or get underwritten at the long-term rental rate — which may be significantly lower than your actual income. Lender selection is the first decision, not the last.
Which Idaho Markets Are Strongest for Short-Term Rentals?
Idaho has some of the strongest STR markets in the Northwest — and it's still one of the fastest-growing states in the country, with the U.S. Census Bureau ranking Idaho among the top states for population growth in its 2020–2023 estimates. That in-migration feeds both housing demand and visitor traffic:
- Coeur d'Alene / Sandpoint: Lake and mountain recreation draws strong STR demand, especially summer. Lakeview properties command premium nightly rates.
- Sun Valley / Ketchum: Year-round resort market with ski season and summer outdoor demand. High ADR (average daily rate) but also high acquisition cost.
- McCall: Popular lake town with strong summer and winter seasons. Lower entry price than Sun Valley with solid STR performance.
- Boise: Growing urban STR market driven by events, Boise State, and business travel. Typically lower nightly rates than resort markets but higher occupancy.
What Are the Key Underwriting Differences for STR?
| Factor | Long-Term DSCR | STR DSCR |
|---|---|---|
| Income documentation | Lease or 1007 | Operating history or AirDNA |
| Minimum lender options | Many | Fewer, specialized |
| Income haircut | None (uses full rent) | Often 25–30% applied to gross |
| Minimum DSCR | Often 1.0 | Often 1.10–1.25 |
| Rate premium | Standard | Typically +0.25–0.50% |
| HOA / STR restrictions | Not relevant | Must confirm STR is permitted |
What STR Restrictions Should I Check Before Closing?
Before financing an STR property, verify:
- Municipal or county STR licensing requirements (some Idaho counties require permits)
- HOA rules — many condos and HOA communities prohibit short-term rentals
- Zoning — some residential zones have STR restrictions
A lender can fund the loan but can't undo a city ordinance that prohibits STR after closing. Do this due diligence before you're under contract, not after.
STR DSCR loans work well when the income is well-documented, the market is established, and you're working with a lender who specializes in the product. The key is knowing which lenders fit before you apply — not after you've spent two weeks with the wrong one.
Frequently Asked Questions
Can I use projected Airbnb income to qualify for a DSCR loan?
Yes, but only with lenders that accept short-term rental income. Some allow projected income from third-party data providers like AirDNA, while more conservative lenders require 12 months of actual booking history. Many DSCR lenders won't accept STR income at all and will underwrite the property at its lower long-term rent.
Do all DSCR lenders finance short-term rentals?
No. A large share of DSCR lenders require a long-term lease and won't count STR income. If you apply with one of these lenders on an Airbnb property, you're either declined or underwritten at the long-term rental rate. Choosing an STR-friendly lender is the first decision, not the last.
How much lower is my qualifying income if I use STR data?
Lenders that accept STR income often apply a haircut of roughly 25–30% to projected gross revenue to account for vacancy, seasonality, and operating costs. That means your qualifying income is meaningfully lower than your best-month gross. Expect the deal to be evaluated on net-of-haircut numbers.
What DSCR ratio do STR lenders require?
STR programs typically require a higher minimum DSCR than long-term rentals — often 1.10 to 1.25 versus 1.0 for standard DSCR loans. The higher threshold cushions lenders against the income volatility that comes with nightly rentals and seasonal markets.
Are rates higher on STR DSCR loans?
Generally yes. STR DSCR loans usually carry a modest rate premium over long-term DSCR loans because lenders view nightly-rental income as higher risk. The exact premium depends on your credit, LTV, and the lender's overlays, so it's worth comparing STR-specialized lenders directly.
Do I need a rental license or permit for an Idaho STR?
Often, yes. Many Idaho cities and counties require STR registration or permits, and rules vary by jurisdiction. Confirm local licensing, HOA rules, and zoning before you go under contract — a lender can fund the loan but can't undo an ordinance that prohibits short-term rentals after closing.
Can I get an STR DSCR loan on a brand-new purchase with no booking history?
Yes, if you use a lender that accepts projected income from a data service like AirDNA. Without operating history, your options narrow to those programs. Once you have 12 months of documented revenue, more lenders open up and pricing usually improves.
Will an HOA affect my STR financing?
It can. Many condo and HOA communities prohibit short-term rentals outright, which can make the property ineligible for STR income treatment or unfinanceable as an STR at all. Always verify the HOA's rental rules before assuming you can operate — and finance — the property as an STR.
