What a lender is actually underwriting when the collateral is a short-term rental

Question

Lending against a long-term rental is straightforward: a lease and a payment history give a lender something concrete to underwrite. A short-term rental has neither. There is no lease, and the income is a stack of nightly bookings that can go to zero if a town changes its short-term rental rules. So what does a lender actually look at. In practice it comes down to treating the long-term rental value of the property as a floor, then layering nightly income on top of that with real scrutiny, since STR revenue needs to be stress tested rather than taken at face value. Permit status is also worth putting directly into the loan documents rather than leaving it as purely the borrower's problem, since a revoked or unrenewed permit can convert the whole income stream to the long-term floor overnight. A lender who underwrites STR collateral well is pricing for that swing, not assuming nightly bookings behave like a lease.

Two different underwriting approaches exist and they don't produce the same loan.

The conservative one is what @ryanmck27 described. You value the property on long-term rent, because a 30-night-minimum ordinance can arrive and the property still rents to a tenant. That gives a lower loan amount and a much more durable one.

The other approach underwrites the actual short-term income. Lenders doing this typically want twelve months of platform statements plus bank deposits that match, and they'll haircut it, often looking at a trailing twelve months rather than a peak season annualized. Some will accept a market projection for a property with no operating history, and that's the weakest version of the file because the projection is produced by a tool with no obligation to be right. Terms and what any given lender will accept change constantly, so get the actual requirements in writing from the lender before you build a model around them.

On the documents: yes, this can appear. A loan on a property whose income depends on a permit can carry a representation that the permit is current and a covenant to maintain it, and sometimes a requirement to notify the lender of any regulatory action affecting the use. Whether that's enforceable in a particular situation depends on the loan documents and state law, so an attorney in that state should draft it.

The piece worth checking regardless of approach is insurance. A property being used for nightly stays under a standard landlord policy may have no coverage at all when a claim comes, and a lender holding a mortgage on an uninsured property is in a worse position than one holding a mortgage on a de-permitted one. Ask for the declarations page and confirm the policy names the short-term use.

The floor answer is what I've heard most. Underwrite it as if it were a long-term rental, because that's the income you can still get if the permit goes away, and treat the nightly upside as the borrower's margin rather than yours.

The condition of the thing matters more here than on a long-term rental too. Tenant lives with a slow leak for a year, guest posts a photo of it on Saturday and the calendar empties. Deferred maintenance turns into lost revenue much faster.
