Start with a market. See it in one glance.

Revenue as a range, occupancy, nightly rate, the season and how much of the supply holds a permit. The same read for every place, from a metro down to a ZIP.

Entire homes. Revenue bar: the middle half of listing estimates, median marked. As of . “Not measured” means we hold no permit registry there yet, never zero.

Then the whole story, in charts.

Thirteen chapters for every place: legality, earnings, nightly rates, the season, competition, what the top earners have, the risks, and where each number comes from.

Does it hold a permit? We check the city’s own registry.

Most tools only see the listing. Where a city publishes its permit registry, we match every listing to it. Where it doesn’t, we show a gap, never a guess.

94%

of Nashville’s 6,302 checkable listings match a permit. The other 357 are the ones to ask about before you buy. A match is evidence, not a legal opinion.

Listings matched to a permit

Five of these nine cities publish no registry we can read yet. We show that, not a number.

Legality · Nashville

The legality chapter: a donut showing 94% of 6,302 listings matched to a permit and 6% with no permit found, with a note that an unmatched listing is not proof of illegality.
