RARE PRIVATE SANDY BEACH | OCEANFRONT ESTATE | 30 MINUTES TO KEY WEST

A truly extraordinary opportunity on coveted Sugarloaf Beach--over 5 acres of private oceanfront property offering endless open-water views, exceptional privacy and a rare natural sandy beach in the Lower Keys. This remarkable estate includes two County-recognized residential dwelling units with an established history of permitted vacation-rental use, creating a valuable combination of existing residential rights, income potential and future redevelopment opportunity.

The main residence offers 4 bedrooms and 4 bathrooms, complemented by a second 2-bedroom, 2.5-bath residence, currently configured as luxury vacation rentals. A newly reconstructed 430-foot dock with stainless-steel pilings, stainless-steel support beams and composite decking provides exceptional boating access, with approximately 5-foot draft accommodating larger vessels. World-class fishing, diving and boating begin at your doorstep, with American Shoal Lighthouse approximately five miles offshore.

A recent professional environmental and development review identifies existing developed and disturbed areas as particularly valuable for future redevelopment and notes potential to enlarge, replace or substantially reconfigure the two existing residences, subject to applicable approvals. The adjoining vacant parcel also contains a preliminary upland opportunity area identified for further development evaluation, adding another compelling dimension to this exceptional offering.

With its private beach, expansive open-water setting, established residences, vacation-rental history and substantial waterfront infrastructure, this is a rare opportunity to create an extraordinary private compound or reimagine an iconic oceanfront retreat in one of the Florida Keys' most secluded settings.
Future development and redevelopment are subject to applicable governmental approvals, environmental requirements and permitting.
