Description
Turn-Key Duplex on a Wide, Deep Canal - Key Colony Beach
Welcome to one of the most sought-after settings in the Florida Keys -Key Colony Beach -- a private, tucked-away island community known for its quiet streets, boater-friendly waterways, and true Keys lifestyle. This full duplex sits on a impressively wide, clean, deep canal (100 ft across), offering easy access for boats of all sizes and some of the best water views in the neighborhood.
Each side of the duplex mirrors the other in quality and layout: upstairs you'll find 2 spacious bedrooms and 2 full baths, while downstairs offers a convenient pool bath plus a bonus game room/flex space with extra storage -- perfect for kayaks, fishing gear, or beach toys. Both units have been tastefully updated and fully furnished, right down to the dishes, pots, pans, and bedding. Just bring your suitcase.
This property is as flexible as it is beautiful. Rent both sides for strong dual-income potential, create the ultimate family compound with room for everyone, or live in one side while renting the other for built-in income. However you use it, you're getting two turn-key homes in one of the safest, most tranquil pockets of the Florida Keys.
Located just minutes from open water, world-class fishing, and the laid-back charm Key Colony Beach is known for -- this is Keys living at its most effortless.
Two homes. One incredible canal. Endless possibilities.
