Revenue
Gross bookings per Marathon listing averaged $65,446 over the 12 months to September 2026 (Florida average: $39,250), before cleaning, platform and management costs and taxes.
In a typical year, the average Marathon listing brings in $11,400 in March, its best month, and $4,000 in September, its slowest. The three strongest months bring in 34% of a full year's revenue, where an even calendar would give any three months 25%.
In a typical month, a top-quarter listing earns at least 3.2 times as much as a bottom-quarter one.
These are monthly figures for listings active in each month. The annual average above also counts listings that operated for only part of the year, so it runs below twelve times these figures.
March earns about 2.8 times what September does

Profit
Yes, when it's run well. The average Marathon Airbnb took in $65,446 in the 12 months to September 2026, and run by its owner at everyday costs, about $3,500 a month of that is left after running costs, so a home that costs less than that to own or rent makes money. A listing in the top quarter leaves about $6,240 a month.
Cleaning it yourself keeps the $7,180 a year guests pay in cleaning fees, for about $4,100 a month. Handing the listing to a co-host at about 10% of nightly bookings still leaves about $3,010 a month.
These amounts come before housing costs. Where the mortgage or rent is less each month, the difference is profit; a home owned outright keeps it all after property tax, home insurance and any HOA or condo fees.

The busiest tenth of listings are booked about 3.3 times as often as the bottom quarter.

Share of open nights booked, by month, September 2024 to August 2026
The 12-month rate of 43% averages each listing's whole year, slow months included; each month here counts only the listings booked in it.
Nightly rates
The average nightly rate in Marathon, known as ADR (average daily rate), was $538 over the past year, about 61% above the Florida average of $335 and about 68% above the U.S. average of $320. In a typical year, rates peak in February and March at about $555 and bottom out in September and October at about $435.
Prices span a wide range: the top 10% charge about three times the rate of the bottom quarter.
March rates run 28% above September's
Average nightly rate (ADR), by month, September 2024 to August 2026
The 12-month ADR of $538 averages each listing's own rate across its whole year; the monthly points average listings month by month, so the two differ.
RevPAR, or revenue per available night, divides a listing's income by every night it was open to book, so it rises with both price and bookings. In Marathon it averaged $248 over the past year, from about $133 in a typical September to about $366 in a typical February.

Permits
None of the 1,100 active listings in Marathon display a registration, permit or license number. That doesn't mean no rules apply: some places don't ask hosts to show a number on the listing, and listing data doesn't capture every scheme.
Registration, permit, zoning and occupancy-tax rules vary by address and change often, so confirm them with the city or county before buying or listing in Marathon.

Yes, when it's run well. The average Marathon Airbnb grossed $65,446 in the 12 months to September 2026, 67% above the Florida average of $39,250. Run by its owner, with the cleaning fee covering the cleaner and everyday costs for Airbnb's fee, utilities, supplies, upkeep and insurance, $41,966 a year (about $3,500 a month) is left before the mortgage or rent. A home that costs less than that to own or rent makes a profit, and a listing at the top-quarter mark leaves about $6,240 a month. Check a specific home in the Airbnb estimator.
