Property Description
Welcome to Morton Manor, an exceptional gulf-side waterfront estate set on 2.82 private acres where luxury, privacy, and resort-style living come together in this extraordinary Florida Keys compound. Encompassing 7,245 sq. ft. of living space, this property features a 5-bedroom, 4.5 bath CBS main residence accompanied by two detached guest homes and a garage apartment, offering a total of 11 bedrooms and 8.5 baths designed to comfortably accommodate family and guests alike. The main home showcases an open-concept floor plan with expansive living and dining areas, two wet bars, elevator access, multiple laundry areas, and spacious guest accommodations, creating an ideal setting for both everyday living and large-scale entertaining. The detached bungalows and garage apartment provide additional flexibility for extended family, visitors, or exceptional rental opportunities while maintaining privacy throughout the estate. Impact-rated windows and doors, a durable metal roof, and quality construction provide lasting peace of mind. The outdoor amenities rival those of a private resort. Relax beside the pool, gather beneath multiple tiki huts, challenge friends to a game on the pickleball court or putting green and enjoy beautifully landscaped grounds. Boating enthusiasts will appreciate the 100' dock complete with 30-amp and 50-amp shore power, yacht dockage and 10K & 20K lb boat lifts. Positioned on the gulfside, the property offers easy access to world-class fishing, boating, snorkeling coves, sandbars, and unforgettable sunset cruises. Dining, marinas, and shopping are less than ten minutes away, and the Florida Keys Marathon International Airport is approximately 4 miles from the property for seamless private aviation access. Whether you're searching for a private family compound or an exceptional investment opportunity, Morton Manor offers a rare combination of acreage, waterfront living, luxury amenities, and versatility that is seldom found in the Florida Keys.
