Description

Don't miss this unique waterfront RV lot in the sought after Key By the Sea community in Marathon. Lot 48E offers approximately 31.5 feet of canal frontage with an overall lot size of about 31.5 by 40.5 feet, creating the opportunity to design your own RV setup, outdoor living space, or future waterfront retreat in the Florida Keys. The existing 1980 mobile home is in poor condition and the property is best suited for renovation, replacement, or redevelopment, with value primarily in the waterfront lot and boating access. If the current structure is removed, and with proper permits, a Buyer may place an RV on the lot or construct a code compliant structure in accordance with local regulations and community guidelines. Key By the Sea residents enjoy desirable amenities including a boat ramp, waterfront pavilion, clubhouse, and three on site laundry facilities. The association fee is $192 per month, providing an accessible path to waterfront ownership in a central Marathon location. Whether you are seeking a seasonal escape, RV destination, or long term investment, this property presents a rare opportunity to create your own space within a welcoming waterfront Keys community.
