Duck Key Pool Home with Legal Downstairs Living & Exceptional Flexibility. Beautifully updated 4BR/3BA pool home on the desirable island of Duck Key, thoughtfully renovated with permits and designed for comfortable coastal living. A standout feature of this home is the legal, permitted downstairs living area (pre-1973), which offers a private space complete with a living room, bedroom, bath, and kitchenette. This flexible layout is ideal for extended family, long-term guests, or creating a separate retreat within the home--an increasingly rare advantage in the Florida Keys. Upstairs, the main living area features updated finishes and generous closet space throughout, providing both comfort and functionality. The home is offered fully furnished and move-in ready, allowing for immediate enjoyment. Step outside to your own private tropical setting, featuring: a sparkling pool and tiki hut for entertaining; lush landscaping with pineapple, fig, starfruit, and avocado trees; a private putting green; and partial Atlantic Ocean views. Additional highlights include two attached garage spaces and access to a voluntary homeowners clubhouse. Conveniently located near Duck Key Marina and Hawk's Cay Resort amenities, with optional memberships available. A rare opportunity to own a versatile, move-in-ready home in one of the Florida Keys' most sought-after communities.
