Marathon's Mermaid Manor is a waterfront home that truly lives up to its name. It is the kind of place that makes people stop scrolling, not because it is flashy or overdone, but because it feels rare and real. Set in the highly desired Sombrero Golf Course neighborhood, this property offers a combination that is hard to find in the Florida Keys, a beautiful home, a prime waterfront setting, strong elevation, and a layout that makes everyday life easy while still feeling special. Inside, you will find three bedrooms, each with a private en suite bathroom, plus an additional half bath off the living room for guest convenience. The spacious open floor plan is built for easy living and entertaining, with the kitchen as the true centerpiece. Custom designed with hickory cabinetry, granite countertops, Wolf cooking appliances, a full size Sub Zero fridge and freezer, a 105 bottle wine cooler, and a Miele espresso machine, it is both beautiful and functional. The oversized island seats four and includes smart built in storage to keep everything organized and clutter free. Outside, enjoy a fully screened in pool deck with a built in outdoor kitchen, plus 125 feet of recently repoured dockage with a 15,000 pound boat lift, davits, and two 50 amp shore power stations, along with immediate Ocean and Gulf access for the ultimate Florida Keys boating lifestyle. One of the biggest advantages of this home is its rare ground level, above flood construction. That alone makes it stand out, but the high and dry elevation makes it even more desirable. With new impact windows and doors, a metal roof, and a whole house generator, the major upgrades are already done, offering comfort, confidence, and true peace of mind for Keys living.
