About this property
Waterfront duplex opportunity on Sombrero Beach Road in Marathon, just about 1 mile from Sombrero Beach. This stilted full duplex offers 4 bedrooms, 4 bathrooms, 2,114 square feet of interior living space, a pool, 110 feet of concrete seawall, dockage, and deep-water boating access. Each side features 2 bedrooms, 2 bathrooms, approximately 1,057 square feet, open living and dining areas, kitchen, washer and dryer, and enclosed sun porch areas with water views. The layout works well for a full-time residence, second home, investment property, or a live-on-one-side and rent-the-other setup. Outdoor features include an in-ground pool, decking, front porch, low-maintenance gravel yard, and a large circular paver driveway with plenty of parking and trailer storage. Boaters will appreciate the 110 feet of dockage with room for multiple vessels. The lower level includes two garages and substantial storage space, ideal for fishing gear, boating equipment, a cabana-style setup, or general storage. With its waterfront setting, duplex layout, pool, dockage, and close proximity to Sombrero Beach, this property offers multiple options in one of Marathon's most desirable lifestyle locations.
