Remarks & Misc

Remarks – Consumer: Two residences, two private pools, and 75 feet of dockage--an inviting combination of space, privacy, and waterfront living in Key Colony Beach. This full duplex brings family and friends together while maintaining the independence of two separate homes. Each offers two bedrooms, two bathrooms, and a generous 1,075 square feet, plus a private entrance, carport, and laundry. Inside, Old Florida character meets modern comfort. Vaulted wood ceilings grace the living, dining, and kitchen areas, while original terrazzo floors in one residence offer a nostalgic nod to the Keys of yesteryear.

Both backyards have been transformed into private tropical retreats, each with its own pool, tiki hut, bar/cabana area, and 37.5 feet of dockage. A connecting gate keeps the outdoor spaces private or opens them for gatherings. Oceanside boating with convenient Gulf access via nearby Vaca Cut. Ideal for extended families and friends sharing a Keys getaway, with room to enjoy one residence while renting the other--or rent both when away. Introduced to the vacation rental market in early 2025, the property has generated and booked $167,000 in 2026 gross rental revenue, with six weeks reserved for owner use. And then there's the location. Just a two-minute walk to Sunset Park, with restaurants and other island amenities an easy walk or bike ride away. A property that brings together the best of Keys living--time on the water, space for family and friends, and the flexibility to enjoy it on your own terms.
Directions: From Overseas Highway, take Sadowski Causeway into Key Colony Beach. Turn right onto W. Ocean Dr, then right onto 11th St. Property will be on your right.
