About This Home

410 85th Street Ocean

Welcome to 410 85th Street Ocean in Marathon, an oceanside waterfront home offering 3 bedrooms, 2 baths, and approximately 1,409 square feet of living space with direct access to the Atlantic. Boaters and anglers will appreciate the 60 feet of canal frontage along a roughly 40- to 45-foot-wide canal, plus the exceptionally quick route to open water--just 654 feet to the ocean. With no long idle out, this is an ideal setup for anyone who wants to spend less time cruising the canal and more time fishing, diving, or enjoying the water. The dock was recapped in 2009 with reinforced cantilevers and sits over cap rock, offering a solid waterfront setup that remains in great condition. New metal boat bumpers have also been added, and the dock enjoys an open-water view. There is 30-amp shore power in place, with the ability to convert to 50 amp if needed. Whether you are looking for a full-time Keys residence, weekend escape, or waterfront retreat designed around boating, this property delivers the kind of immediate ocean access that makes Marathon living so desirable.
