This is the core problem with getting a mortgage on a short-term rental. Most conventional lenders โ and even most DSCR lenders โ default to the appraiser's long-term market rent when underwriting your property. For a beach house or mountain cabin that earns $4,800/month on Airbnb, the long-term market rent might be $1,600. That's the number they use. That's why deals that should work easily get denied or come back with much lower loan amounts than they deserve.
The right approach: qualify on what the property actually earns as an STR
We accept AirDNA income projections for short-term rental DSCR loans. AirDNA aggregates real Airbnb and VRBO booking data โ actual nightly rates, occupancy rates, and seasonal patterns โ for comparable properties in your specific market. That income figure reflects what your property can realistically earn as an Airbnb, not what it would earn with a long-term tenant paying below-market rent. For most STR investors in vacation markets, this produces a DSCR ratio that is substantially stronger than the long-term rent method โ often making the difference between approval and denial.
