Description

This property is a double lot listed at land value, offering 15,763 square feet with two separate folios and 162 feet of open water frontage. Located in Duck Key, the site provides the opportunity to build two separate homes, each with open ocean views, creating flexibility for future development or investment. The existing residence features 4 bedrooms, 5 bathrooms, and 3,072 square feet of interior space. Built in 1986 with solid construction and a metal roof, the home is positioned to capture water views throughout. An extensively large balcony overlooks the open ocean, expanding the outdoor living space and taking full advantage of the waterfront setting. The layout centers around the views, with expansive windows bringing in natural light and connecting the main living, dining, and kitchen areas. Seventeen windows and seven impact doors were replaced last year, adding to the property's recent improvements. Duck Key is one of the few communities in the Florida Keys that allows monthly rentals, offering flexibility for owners seeking personal use or income potential. Residents enjoy boating access, clear waters, and nearby amenities at Hawks Cay Resort, including dining, marina services, and resort experiences. Whether used as it stands, updated over time, or redeveloped into two separate residences, this double lot presents a rare opportunity to secure open ocean frontage in one of the most established communities in the Keys.
