Revenue
Gross bookings per South Portland listing averaged $33,104 over the 12 months to September 2026 (Maine average: $37,768), before cleaning, platform and management costs and taxes.
In a typical year, the average South Portland listing brings in $6,930 in August, its best month, and $1,710 in March, its slowest. July runs within 5% of August, so either can come out on top in a given year. The three strongest months bring in 41% 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 2.8 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.

Profit
Yes, when it's run well. The average South Portland Airbnb took in $33,104 in the 12 months to September 2026, and run by its owner at everyday costs, about $1,870 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 $3,010 a month.
Cleaning it yourself keeps the $2,520 a year guests pay in cleaning fees, for about $2,080 a month. Handing the listing to a co-host at about 10% of nightly bookings still leaves about $1,610 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.
