Median days on market

Marathon sits right in the heart of the Florida Keys, a stretch of Middle Keys islands built around fishing, boating, and easy access to both the Atlantic and the Gulf. Neighborhoods like Coco Plum Beach draw buyers who want deep water at the dock and a shorter commute to the flats than you'd find further down the chain. It's a place where a boat is less a luxury than a lifestyle, and the waterfront homes reflect that priority.

Right now the market here is thin and high-end: just 3 active single-family homes, all of them above $1M, with a median list price of $3,495,000. Two of the three are waterfront and two include a pool, and homes are moving in a median of 20 days. If you're shopping this pocket of Monroe County, expect to compete for a handful of premium properties rather than browse a deep inventory.

Marathon is in Monroe County, Florida.

Marathon real estate FAQs

Is Marathon a good place to live?+

Marathon works best for buyers who center life around the water — fishing, boating, and quick access to both the Atlantic and the Gulf from the Middle Keys. Families are served by Marathon School and Stanley Switlik Elementary School, and communities like Coco Plum Beach give the island a settled, residential feel.

Is Marathon expensive?+

Yes — every active listing is above $1M, and the median list price is $3,495,000. This is a small, high-end market, so you're buying into luxury homes rather than entry-level property.

What do homes cost in Marathon?+

Current active single-family homes range from $2,100,000 to $3,690,000, with a median around $3,495,000. At roughly $1,077 per square foot on a median home size near 2,964 sqft, waterfront access and lot position drive most of the pricing.

How is the Marathon market right now?+

Inventory is very tight — only 3 active listings at the moment — and what's available is moving in a median of 20 days. Two of the three are waterfront homes and two are new construction, so serious buyers should be ready to act quickly.

What about HOA fees and property taxes?+

The median HOA here runs about $550 per month, and median property taxes land near $16,843 per year, reflecting the high assessed values of these waterfront properties. Budget for both alongside the purchase price when you evaluate a home.
