Marathon sits in the heart of the Florida Keys, a working island town in Monroe County where boat ramps, dive charters, and canal-front backyards shape daily life more than any downtown. Neighborhoods like Coco Plum Beach lean toward single-family homes built for people who want direct water access, a place for the skiff, and easy sunsets. It's the kind of place where your commute might be by boat and your kids attend Marathon School or Stanley Switlik Elementary.

The market here is small and unmistakably high-end. There are just 2 active listings right now, both luxury homes ($1m+), with a median list price of $2,844,500 and a range from $1,999,000 to $3,690,000. With only 3 homes sold in the past year and sellers getting 96% of asking, you're negotiating in a thin market — so it pays to browse by price and move decisively when the right one lands.

Marathon is in Monroe County, Florida.

Marathon real estate FAQs

Is Marathon a good place to live?+

If your life revolves around the water — boating, fishing, diving — Marathon is one of the most livable spots in the Middle Keys, with residential pockets like Coco Plum Beach and assigned schools including Marathon School and Stanley Switlik Elementary. It's a smaller, working island community rather than a resort strip, which suits buyers who want a real neighborhood on the water.

Is Marathon expensive?+

Yes — it's firmly a luxury market. The median list price is $2,844,500 and every active listing is over $1 million, so plan for pricing that reflects scarce, water-oriented luxury homes ($1m+).

What do homes cost in Marathon?+

Current listings range from $1,999,000 to $3,690,000, with a median around $2,844,500 and an average of about $1,073 per square foot. Over the past 12 months the median sold price was $1,360,000, so there's meaningful spread between what recently closed and what's listed today.

How is the Marathon housing market?+

It's small and tight — just 2 active listings and 3 sales in the past year. Homes take a median of about 40 days to sell and sellers are getting 96% of asking, so serious buyers should watch new inventory and just reduced listings closely.

What about HOA fees and property taxes?+

HOA data isn't available for the current listings, which is typical for the single-family homes that make up the inventory here. The median annual property tax runs about $10,402, in line with high-value Keys real estate in Monroe County.
