How a Lender Defines "Market Rent" for a Short-Term Rental

Market rent in a long-term context, quickly

For a long-term rental, market rent is generally a monthly figure: what similar properties nearby are actually leasing for, adjusted for differences in size, condition, and location. It's a single number, relatively stable month to month, and directly comparable across properties.

That stability is part of what makes the long-term definition so easy to work with. A market rent figure established in January is still a reasonable estimate in June, because long-term rents don't swing much within a single year. The whole concept assumes a kind of steadiness that a short-term rental simply doesn't have.

It's also a concept most borrowers already intuitively understand from renting an apartment or evaluating a standard buy-and-hold rental property. That familiarity is actually part of what makes the STR version confusing the first time you encounter it — the phrase sounds the same, so it's easy to assume it works the same way, right up until you notice there's no lease anywhere in the file to point to.

Why that definition doesn't transfer directly to an STR

A short-term rental doesn't have one rent — it has 365 of them, one for each night, varying by season, day of week, and demand. There's no single figure that captures "the rent" the way a lease does. So when a lender talks about market rent for an STR, they're generally not talking about a nightly rate at all — they're talking about an annualized revenue equivalent, built by combining an estimated occupancy rate with an estimated average daily rate across a full year.

• It's typically expressed as an annual total (or a monthly average derived from that annual total) rather than a fixed nightly or monthly figure.
• It incorporates an assumed occupancy rate, not just a rate — a property with a high nightly rate but low occupancy can have the same market rent equivalent as one with a lower rate and higher occupancy.
• It draws on both comparable STR listings and, often, an appraiser's adapted rent schedule rather than a single comparable-lease approach.
• It's inherently an estimate reconciled from multiple sources, rather than a figure with one clean, authoritative origin.

It helps to think of the STR version of market rent less as a single fact and more as a modeled equivalent — a way of translating a genuinely variable income stream into a single number that can be compared against a fixed monthly debt payment. That translation is necessary for the underwriting math to work, but it's worth remembering that the number itself is a construction, not a discovery.

What this means practically for your loan file

When your lender references a "market rent" figure for your STR application, it's worth asking directly what that number represents — whether it's the market-projection tool's annualized estimate, the appraiser's rent-schedule figure, your own trailing 12-month average, or some reconciliation across sources. The label sounds simple; the number underneath it usually isn't a single clean data point.

This matters most when you're comparing offers or requirements across more than one lender. Two lenders both citing a "market rent" figure for the same property might be referencing different sources, different reconciliation methods, or different levels of conservatism applied on top of the raw estimate. Asking each lender to be specific about their methodology is a small amount of friction upfront that avoids confusion later in the process.

It's also worth understanding that this figure isn't necessarily fixed once it's set at application. If your DSCR loan program reviews qualifying revenue again at any later point — for instance at a rate reset, an assumption, or a subsequent refinance — the market rent figure may be recalculated using updated comparables or updated operating history. Treating the number as a one-time snapshot rather than something that could be revisited later can lead to an unpleasant surprise if the property's performance, or the surrounding market, has shifted meaningfully by then.
