Property Description
Discover this beautifully updated full duplex in the heart of Marathon, set on an oversized 10,000 sq ft lot among mature native trees that provide shade and privacy year-round. Elevated on a stilted structure with a concrete roof, this solid CBS concrete construction property offers durability, peace of mind, and long-term value. Each unit has been fully remodeled with white terrazzo floors, granite countertops, and stainless steel appliances, creating a clean, modern coastal feel. Recent upgrades include new HVAC systems and impact windows for added comfort, efficiency, and storm readiness. This duplex has a strong income history, previously grossing approximately $69,000 annually. One side is currently being left vacant for easy showings, making this an excellent opportunity for investors, employee housing, or living in one unit while renting the other. The elevated design, concrete roof, and oversized lot make this property both practical and appealing, offering valuable space for parking, storage, or business use. With four covered parking bays under the homes, there is excellent potential for additional storage or the option to create fully enclosed garages. This flexible setup makes the property especially attractive for employee housing, providing peace of mind for your staff along with usable square footage and room to support personal or business needs. Centrally located near shopping, dining, marinas, and beaches, this is a rare multifamily opportunity in the Florida Keys.
