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

Discover a luxurious oceanfront haven on Duck Key, Florida, listed at $5,250,000. This 4-bed, 4-bath, 3,417 sq ft home on a 10,070 sq ft lot in Plantation Island blends elegance with island charm. Built in 1965 and exquisitely updated in 2019 with brand new AC, Electric and Plumbing. It features shell stone-wrapped walls, iceberg marble floors on the first level, and onyx marble upstairs, with a book-matched slab in the master suite. The gourmet kitchen boasts a La Cornue gas stove, ideal for hurricane season. Enjoy 72 ft of deep-water dockage with 20,000 lb and 10,000 lb boat lifts, coral stone steps to a canal, and access to a private Duck Key boat ramp ($10 fee) and marina for safe storage and fueling. Fish for tuna, mahi-mahi, and snapper near deep ocean drops and humps, with easy bayside access via nearby bridges. Lush mango, guava, and plantain trees, plus bougainvillea, create a tropical oasis. Duck Key, 60 miles from Key West and 100 miles from Miami, offers 230 sunny days, 70s-90s temps, and no state income tax. Join the optional Duck Key clubhouse for a pool, tennis, pickleball, and events, or Hawks Cay Resort for its Michelin-rated Salt and Ash restaurant, saltwater lagoon, Dolphin Connection, and pools. Relax at Grassy Key Sandbar or dive into vibrant marine life with dolphins and manatees. With top schools and a tight-knit community, this home, steps from the island's entrance, features calacatta stone, Restoration Hardware furniture, and marble baseboards. Cash, conventional, or seller financing available.
