Property Description
The Building Right Is Secured. The Site Is Prepped. The Dock Is Done. Utilities Are In. The Only Thing Left Is the House. For buyers who have dreamed of building a custom home in the Florida Keys, this is an opportunity to skip much of the time, uncertainty, and groundwork that typically comes before construction can even begin. The hard work has already been done. The building right is secured, the lot has been cleared, fenced, and prepared, the geotechnical survey is complete, and both the electric and water meters are installed. On the waterfront, the dock permit is complete and a brand-new dock is already in place along 75 feet of canal frontage. This homesite is ready for the next step: building your Florida Keys home. Located in a desirable Marathon waterfront neighborhood surrounded by attractive homes, the property also delivers the lifestyle you're building for. Enjoy quick and convenient boating access to the Gulf, putting fishing, diving, cruising, and days at the sandbar within easy reach. Weekly vacation rentals are also permitted, giving you the flexibility to design a full-time residence, private Keys getaway, or income-producing vacation home. Instead of purchasing a vacant lot and beginning the lengthy process of preparing it for construction, start with the groundwork already behind you and focus on what matters most--designing and building the home you want. The building right is here. The infrastructure is here. The dock is waiting for your boat. Now bring your plans and build your Florida Keys dream home.
