About This Property

Welcome to your waterfront dream home in the heart of Key Colony Beach! This beautifully renovated 3 bedroom, 3 bathroom single-family home is a private tropical retreat.

Relax in your own backyard oasis featuring a saltwater pool with both heater and chiller, a spacious tiki hut for entertaining, and lush landscaping that enhances the serene island ambiance. The large screened-in porch, complete with a stunning epoxy floor, provides an inviting space to lounge while enjoying gentle breezes and waterfront views. Inside, the home was fully remodeled between 2017 and 2018 with no detail spared. The open-concept kitchen is outfitted with quartz countertops, stainless steel appliances, custom cabinetry, and stylish tile finishes. Porcelain tile flooring flows throughout, and every window and door is impact-rated for peace of mind. 3 bedrooms and 3 baths offer plenty of space for your and guests. The one-car garage adds extra storage space for gear, bikes, or paddleboards. As an active vacation rental, this home is turnkey and income-producing, with a strong rental history and excellent guest appeal. Brand new HVAC system and Hot Water heater. Rubber seal on roof was done in 2023 with new gutters added.
