Airbnb and Short-Term Rental Loans: Financing a Vacation Rental Property | Wise Capital Mortgage

Short-term rentals generate more income than a traditional lease, but they also get underwritten differently — and picking the wrong lender is the most common reason a strong Airbnb deal gets denied.

Why traditional underwriting undervalues Airbnb income

Many general-purpose DSCR lenders calculate short-term rental income using long-term rent comparables, which can badly understate a property's real cash flow. A property grossing $5,000+/month on Airbnb might show a long-term comparable rent of half that, causing the deal to fail DSCR on paper even though actual cash flow is strong. Choosing a lender who underwrites short-term rentals correctly is the single most important decision on these files.

Three ways lenders document STR income

12-month platform history. The strongest method — actual Airbnb or VRBO statements showing gross rents collected over the trailing 12 months. Only available on a refinance of an already-operating property, not a purchase.

Market data tools (like AirDNA). STR-friendly lenders use market-derived short-term rental revenue projections based on comparable properties, which supports purchase transactions before you have your own operating history.

Appraiser short-term rental schedules. Some appraisals include a short-term rental income comparison alongside the standard long-term rent survey.

Check Local Rules First
Your target market must actually permit short-term rental use. Many Texas cities and HOAs regulate or restrict STR activity — confirm zoning and any permit requirements before you count on Airbnb income in your underwriting.

What to expect on terms

Short-term rental DSCR loans typically carry a modest rate premium over long-term rental DSCR pricing, along with a similar 20-25% down payment range, to account for income volatility across seasons.
