The question that decides most short-term rental deals is not the rate. It is how the lender counts your income — and that varies more between lenders than almost any other underwriting factor.
These questions cover income treatment, leverage, and regulatory risk on STR properties.
Quick answer
Lenders treat short-term rental income three ways: actual booking revenue, discounted booking revenue, or substituted long-term market rent. A property earning $6,000 monthly in bookings might be underwritten at $3,200 in market rent — which can change whether it qualifies at all.
Frequently Asked Questions
Can I get a DSCR loan on a short-term rental?
Yes, many lenders offer STR programs. The critical variable is how they count the income, which you should confirm in writing before applying.
How do lenders count STR income?
Three common approaches: actual documented booking revenue, actual revenue with a discount applied, or substituted long-term market rent regardless of what the property earns.
Which approach is most favorable?
Actual booking revenue. On a property performing well as an STR, using documented revenue rather than long-term market rent can be the difference between qualifying and not.
Why do lenders discount STR income?
Short-term revenue is seasonal and variable compared to a twelve-month lease. Discounts and market rent substitution are how lenders account for that volatility.
What documentation supports actual revenue?
Platform statements from Airbnb, Vrbo, or your booking system, ideally covering twelve months to capture seasonality. Tax documents showing the income also help.
What if the property has no operating history?
Expect conservative treatment. Without documented performance, most lenders will use long-term market rent or a projection they consider defensible.
Can a market rent study help?
Some lenders accept third-party STR revenue projections from recognized data providers. Acceptance varies, so ask before commissioning one.
Is leverage lower on short-term rentals?
Frequently yes. STR LTV caps are commonly tighter than standard rentals, meaning more down payment for the same property.
Are reserves higher?
Often, reflecting income seasonality. A property with strong summer revenue and weak winter months needs reserves to cover the lean period.
Are rates higher on STR properties?
Typically somewhat, reflecting the additional risk from income variability and regulatory exposure.
How does local regulation affect financing?
Considerably. Lenders assess whether short-term rentals are permitted and stable in your market. Cities that have restricted or banned STRs create real risk to the income the loan depends on.
What if regulations change after I buy?
This is the core STR risk. A regulatory change can eliminate the income stream the loan was underwritten against. Model whether the property works as a long-term rental as a fallback.
Should I check zoning before buying?
Absolutely. Verify the specific property's eligibility for short-term rental use — permits, registration requirements, occupancy caps, and any pending regulatory proposals.
Do HOA rules matter?
Yes, and they are frequently overlooked. Many associations prohibit or restrict short-term rentals regardless of what local law permits. Check the CC&Rs directly.
Can I finance a property currently operating as an STR?
Yes, and the operating history is an advantage. Documented revenue is much stronger evidence than a projection.
Does furnishing count toward the loan?
Generally not. DSCR loans finance real property. Furniture and equipment are typically your own capital outlay on top of the down payment.
What is the biggest STR underwriting mistake?
Assuming the lender will use your actual booking revenue. Many will not, and discovering that after an appraisal comes back is expensive.
Should I model both income scenarios?
Yes. Run the coverage ratio using actual STR revenue and again using conservative long-term market rent. If the deal only works on the STR number, understand the exposure.
Is a mid-term rental treated differently?
Sometimes. Thirty-day-plus furnished rentals occupy a middle ground and some lenders treat them more like long-term rentals. Ask specifically.
What single question should I ask every lender?
Will you use my documented booking revenue, a discounted figure, or long-term market rent? That answer determines your qualifying number more than anything else.
