Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map — verify navigability with a local captain or surveyor before relying on it.

Description

Welcome to modern coastal living in Key Colony Beach, one of the true gems of the Florida Keys. This fully remodeled pool home blends a clean, contemporary style with an easy, open layout that feels tailor-made for the Keys lifestyle. Sitting on a rare 16,725 sq ft lot—about twice the typical size—and on the highly desired west side of the island, there’s ample room for multiple vehicles, trailers, and even an RV. The solid CBS stilt home is surrounded by lush landscaping and fruit trees for a private, tropical setting. Inside, cathedral ceilings make the 3 bed, 2 bath, 1,775 sq ft floor plan feel even more spacious. Nesting sliders open to a large screened porch, new outdoor kitchen, and multiple seating areas around the pool, creating a seamless indoor-outdoor flow that’s ideal for entertaining. Set on an enchanting corner lot just minutes from open water, you’ll enjoy cooling ocean breezes and a short stroll to Sunset Beach Park for nightly sunsets. Boaters will love the 50' concrete dock with 50-amp power and water, with quick access to both the ocean and Bay via Vaca Cut—putting the Vaca sandbar, fishing, diving, and snorkeling all a short boat ride away. With an adjustable-temperature pool for year-round use and 7-day rentals allowed, this property works beautifully as a personal retreat, income-producing vacation rental, or a combination of both. It’s a turnkey Keys home in one of Key Colony Beach’s most coveted locations.
