Private Florida Keys Island Listed for $16 Million with Helipad and Dock
A secluded island off Marathon, Florida, featuring a main house, guest cottage, helipad and private dock has been put back on the market for $16 million.
An exclusive island situated a quarter-mile from Marathon in the Florida Keys is again for sale at $16 million, after previously being listed at $11.7 million in 2021. The parcel comprises a 2,304-square-foot primary home, a separate one-bedroom guesthouse, a private helipad, a large dock, and roughly 5.8 acres of seabed rights that include reef and snorkeling areas. Listed by Vladimir Rochebrun and Aaron Rosenthal of The Chad Carroll Group, Compass, the island runs on its own solar and wind systems, providing fully off-grid power.
Recent improvements include a major kitchen remodel and overall careful upkeep, giving the property a well-loved feel. Rental history shows weekly rates of $13,500, with higher prices of $17,500 during peak holidays, making it both a personal retreat and a revenue-generating asset. Proximity to Marathon allows residents to reach a grocery store within three minutes and reach the mainland in minutes by boat, jet ski, or helicopter.
Why it matters
The sale highlights a rare ultra-private, self-sustaining island offering both luxury living and investment potential.
