    What's special

    Secured gulf front estateTen bedroomsHelicopter landing padGreat roomGame roomProtected boat slip
    Casa Mañana Shores, located in the heart of Marathon, is a developer's dream or a private owner's potential paradise. This secured gulf front estate offers 3.86 acres of land and is surrounded by an eight foot concrete wall with three gated entrances. The property boasts approximately 540 linear feet of Highway frontage and 695 linear feet of water frontage. It offers 218 feet of concrete seawall, including a cut-in protected boat slip. There is even room for a helicopter landing pad to be installed. This unique property is zoned mixed-use commercial and comes with one commercial transferable building right. It is currently a private residence with a separate garage and workshop. The 10,852 square foot mansion is solid concrete construction. It has ten bedrooms, six and a half bathrooms, a sauna, game room and great room. Repairs are needed, and the interior needs significant updating. An attached partially screened enclosure holds an impressive 12 ft deep swimming pool that measures 25 x 50 ft. The garage/workshop is a separate structure with two rooms with a mini split air conditioner. The existing structures could be demolished for those with a vision, leaving you with a 3.86 acre blank canvas in the center of town. Its versatile zoning designation offers multiple possibilities for residential and/or commercial use. Over the years it has previously housed a motel with a marina, a 19-unit trailer park, and a restaurant. This property presents the opportunity to create the ultimate secluded retreat of your dreams!
