Beautifully renovated and fully turnkey duplex located on a deep-water canal in the heart of Marathon. This rare income-producing property features two spacious 2BD/2BA units, each offering approximately 927 sq. ft. of updated coastal living with impact windows and doors, granite countertops, stainless steel appliances, tile flooring throughout, and covered parking. Renovated in 2018, the property blends modern finishes with the relaxed Florida Keys boating lifestyle.
A true boater's dream, each side offers its own 30' concrete dock and seawall (60' total) complete with 30-amp shore power. Enjoy quick ocean access and easy Gulf access via Vaca Cut, making this an exceptional setup for anglers and boating enthusiasts alike. The waterside outdoor spaces are designed for entertaining and enjoying the Keys lifestyle, featuring string lighting, solar-lit dock pilings, under-dock fish lights that attract snapper and tarpon, and frequent manatee visits along the canal.
Located directly adjacent to Oceanfront Park & Dog Park, owners and guests enjoy immediate access to one of Marathon's premier waterfront parks offering a dog park, kayak launch, open green space, waterfront walking areas, playgrounds, and frequent community events. Conveniently located near Sombrero Beach, shopping, dining, and Florida Keys Marathon International Airport.
Currently tenant occupied with both units rented month-to-month. This property also has strong vacation rental potential. Ideal opportunity to live in one side while renting the other, or maximize income potential with a fully turnkey investment property in one of the Florida Keys' most desirable boating communities.
