Island living meets boating paradise in this updated 2-bedroom, 2-bath half-duplex in Key Colony Beach.

Inside, the home features Corian countertops, Whirlpool stainless steel appliances, a Rheem tankless hot water heater, and an energy-efficient multi-split Daikin A/C system. A brand-new 2025 Whirlpool washer and dryer add modern convenience. Boaters will love the ability to dock a vessel up to 50 feet, with conduit already installed for future dockside water and electric. With quick access to both the Atlantic Ocean and Gulf through Vaca Cut, your next fishing or sunset cruise is always minutes away. Ideally located directly across from the Key Colony Beach Golf Course and nearby tennis, pickleball, bocce courts, and playground, this property offers the perfect blend of waterfront relaxation and active island living.
