Description

With only two owners in its history, this well-maintained two-story property presents a rare investment opportunity in Key West. Configured as a legal duplex with two separately metered 1-bedroom, 1-bath units, it offers exceptional flexibility--ideal for investors seeking strong rental potential, business owners looking for employee housing, or owner-occupants wanting to offset costs by renting one unit while living in the other. Set on a 5,000 sq ft lot, the property is surrounded by lush, mature tropical landscaping with a wide variety of plants and palms, creating a private, shaded, treehouse-like setting filled with natural light. Two large screened porches and additional open-air spaces provide ideal indoor-outdoor living, while an outdoor shower enhances the island lifestyle. The home has been thoughtfully updated and well cared for, featuring Mitsubishi mini-split A/C systems in both units, a new hot water heater, new ceiling fans, impact windows upstairs, new gutters, updated appliances, and soft-close cabinetry. Interior finishes include a mix of pine, vinyl, and concrete flooring, along with stainless, Formica, and butcher block countertops. Both units offer full bathrooms with tubs. Additional highlights include two off-street parking spaces, low-maintenance grounds, and multiple windows throughout for abundant natural light and airflow. Located in desirable Midtown East, just minutes from everything Key West has to offer, this is a versatile, income-producing property with strong upside potential.
