Two Rental Dashboards, One Sevierville Cabin: Why the Revenue Estimates Don't Agree

"Regulation is low with minimal registration requirements, pointing to an operator-friendly environment." That is how AirROI's Sevierville market report, updated September 12, 2026, describes the town to an investor shopping for a cabin. The same report says about 0.1% of the listings it tracks show any registration evidence.

Inside city limits, the City of Sevierville requires a Short-Term Operational Permit that lasts one year and has to be applied for again every year. It also requires a life-safety inspection by the Fire Marshal's office before the permit is approved. If the property sits in the Medium Density Residential zone, the city notifies every property within 100 feet, and an objection sends the application to a public hearing before the Planning Commission.

Nothing about that process is minimal. The dashboard got it wrong because it never read the city's rules. It guessed at regulation from how hosts write their listings. The same blind spot shapes every other number these tools publish about Sevierville this year. In 2026, a dashboard's Sevierville trend line tells you more about how that company counts than about what a cabin earned.

Same town, about the same size, two different years

Put the two best-known public dashboards next to each other and they agree on one thing: how big the market is. On almost everything else they split.

The AirDNA Sevierville page and the AirROI Sevierville report cover nearly the same twelve months and count nearly the same number of rentals. They still land about $19,300 apart on what a typical listing earned. One says supply shrank by almost half. The other says it grew by more than 40%.

For a buyer, that gap is the whole deal. On a cabin priced off its income, $19,000 a year can be the difference between a property that carries itself and one that needs a check from the owner every month.

How revenue climbs while every night earns less

The AirDNA figures contain a puzzle worth working through slowly. From September 2025 to September 2026, AirDNA reports Sevierville's average daily rate down 6.9%, occupancy down 0.4%, and RevPAR down 5.9%. Over the same stretch, it reports annual revenue per listing up 25.7%.

RevPAR is the earnings of each night a rental is open for booking. AirDNA defines it as occupancy multiplied by daily rate and calls it "the truest measure of earning power per available night." If each available night earned about 6% less, the typical listing can only bring in about 26% more over a year in two ways. Either it was open far more nights, or the set of listings being averaged changed.

The listing count points to the second answer. A 45.8% drop in active listings means the average was spread over a very different group of properties than a year earlier. Take out a large share of the part-time or weaker listings and the "average listing" earns more, even if no individual cabin did.

The ruler moved in June

AirDNA documented two changes in June 2026, both inside the year-over-year window behind those Sevierville numbers.

1. New market boundaries. A June 9, 2026 help article says U.S. markets "are no longer defined by cities or zip codes but by specific areas," and gives the example of several separate Poconos towns folded into one market with submarkets.
2. New data sources and matching. A June 12, 2026 update says Booking.com data became part of the product that month, alongside Airbnb and Vrbo. It also introduced Model 5.0, with a matching sub-model that removes duplicate listings across platforms and a reservation algorithm that "distinguishes guest bookings from host-blocked days."

Every one of those changes affects what gets counted as a listing, what counts as a booked night, and where the market's edges fall. AirDNA's boundary article and data-update log don't say whether Sevierville's own boundary moved. So no one outside the company can confirm the drop is a measurement break. It is a plausible one, and it fits the arithmetic above better than the idea that nearly half of Sevierville's rentals vanished in a year while the survivors earned a quarter more.

AirROI runs on a different base. Its report describes itself as Airbnb data. It lists Pigeon Forge, Gatlinburg and Wears Valley among the "neighborhoods" on its Sevierville page without defining where the market's edges are. Two firms counting different platforms inside different, undisclosed boundaries can each be internally consistent and still describe different places under the same name.

What the ground-level numbers say

Neither dashboard can be checked against a Sevierville-only lodging figure for 2026, because the research turned up no published city or county lodging-tax series for this year. The nearest public numbers still say something about which direction the year went.

The Tennessee Department of Tourist Development's 2025 Economic Impact of Travel report, released in September 2026, puts Sevier County's visitor spending on lodging at $1,530,651,042 for calendar year 2025. That is up 1.6% from $1,506,744,479 in 2024. Total direct visitor spending in the county was $4,090,908,818 in 2025, up 3.2%. The report covers all lodging, hotels included, so it is a ceiling on the cabin story rather than a measure of it.

Next door in Pigeon Forge, WVLT reported in May 2026 that preliminary data through March 2026 showed lodging revenue "essentially flat" at $75,085,789. That held even though the city had added more than 1,600 new hotel rooms since 2024.

"We're holding our own," said Amy Warner, interim director of tourism for Pigeon Forge. "Being able to say that we're slightly up, we're holding our own with lodging, we'll take it."

A county lodging total growing 1.6% a year, plus a neighboring city adding hotel rooms into flat lodging revenue, describes a market where the money is being split among more beds. That picture sits much closer to AirROI's slight revenue decline than to a 25.7% jump in what the average Sevierville rental takes home. It still doesn't prove AirROI's levels are right. Its 42.0% occupancy and $51,876 average come from its own platform mix and boundaries, and the research didn't establish how it defines an available night.

What the dashboard can't see about a specific cabin

That brings things back to the permit. A market average blends cabins that can legally rent with ones that can't, cabins on city land with ones under county rules, and a list of addresses that, in AirDNA's case, may have been redrawn this summer. None of that tells you how a particular cabin on a particular road is set up.

Two sets of rules apply depending on which side of the city line a property sits:

• Inside Sevierville city limits: confirm the address is inside the city and that its zoning allows short-term rental use, using the city's limits and zoning maps. Then comes an annual operational permit, a Fire Marshal life-safety inspection against the Fire Department's Short-Term Rental Unit Checklist, and, in MDR zoning, the 100-foot neighbor notice with the possibility of a Planning Commission hearing.
• Unincorporated Sevier County: the county's short-term rental unit program has required an annual permit and a yearly inspection since January 1, 2024. The fee is $250 for units that sleep 12 or fewer, and $250 plus $25 for each additional occupant for units that sleep 13 or more.

The city's short-term rental page and the county's permit program page lay out each step. A cabin's permit history, inspection record and zoning are facts a seller can document. A market score cannot.

The same goes for income. A cabin's own trailing-twelve-month booking and payout records come from one set of calendars on one property under one set of rules. That makes them the only revenue figure that carries over from a dashboard conversation to an offer. A dashboard is most useful for questions it can answer consistently, like which months run strong and roughly where nightly rates cluster. It is least useful for its year-over-year change line, which is the figure most likely to have been rewritten by a method change.

A few questions buyers ask about Sevierville rental data

Which dashboard is right about Sevierville? Neither one can be confirmed for 2026 from public data. Their market sizes roughly agree, at 7,560 and 7,393 listings. Their trend lines point in opposite directions, and the county and Pigeon Forge lodging figures look more like a flat year than a boom.

Did nearly half of Sevierville's rentals really disappear? No public source found in this research shows a mass exit. AirDNA changed its market boundaries, platform coverage and duplicate matching in June 2026, and its own documentation doesn't say how that affected Sevierville's historical comparison.

Why do the dashboards list occupancy so differently? AirDNA measures occupancy as the share of available nights that were booked, and since June 2026 it has used an algorithm to separate guest stays from owner-blocked dates. AirROI's report doesn't spell out its method, so the 57% and 42.0% figures may not be measuring the same thing.

If you're weighing a Sevierville cabin and the dashboard numbers aren't adding up, Deanna Dellinger can help you pull together what matters for that one property: its actual booking history, its permit and inspection status, and which side of the city line it sits on.
