Florida Keys Private Island Mansion Listed for $16 Million

A private island estate in the Florida Keys, offering unparalleled privacy and accessibility via water or air, has been listed for sale at $16 million. This exclusive property is situated just a quarter-mile off the coast of Marathon, Florida, providing residents with direct access to the Atlantic Ocean's turquoise waters, ideal for a variety of water activities including snorkeling, swimming, kayaking, paddleboarding, and fishing. Despite its secluded nature, the island offers convenient access to the mainland, with travel times of mere minutes via boat, Jet Ski, or helicopter. Vladimir Rochebrun, co-listing agent from The Chad Carroll Group at Compass, highlighted the strategic advantage of the island's location on the ocean side of Marathon, noting it avoids common nuisances like insects prevalent on the Gulf side, thereby enhancing the quality of life and outdoor enjoyment. The property encompasses a 2,304-square-foot main residence with three bedrooms and a separate one-bedroom guesthouse. Significant updates have been made to the primary home since its last listing in 2021. The estate also includes five acres of seabed, a unique feature that underscores the comprehensive nature of the private island ownership. The listing emphasizes the rare combination of extreme privacy and proximity to metropolitan amenities, a characteristic seldom found in similar island properties. The Chad Carroll Group at Compass is handling the sale, with Aaron Rosenthal also serving as a co-listing agent. The property's unique selling points include its water-centric lifestyle, the convenience of private air and sea access, and its desirable location on the Atlantic side of the Florida Keys, which offers a more pristine environment compared to the Gulf side. The inclusion of five acres of seabed with the property further distinguishes it, providing extensive control over the surrounding marine environment. This offering represents a significant opportunity for buyers seeking a luxurious and secluded residential experience in one of Florida's most sought-after coastal regions. The property's accessibility, combined with its extensive amenities and natural beauty, positions it as a premier real estate offering in the Florida Keys market. The sellers have invested in modernizing the main residence, ensuring it meets contemporary standards of comfort and luxury while preserving the island's unique charm. The separate guesthouse provides additional accommodation for visitors or staff, enhancing the property's utility as a private retreat or a high-end rental opportunity. The overall appeal of the estate is amplified by its integration with the surrounding marine ecosystem, offering a lifestyle deeply connected to the ocean.
