A rare combination of land, privacy, boating, and open-water living awaits on approximately half an acre of Gulf-front paradise in Grassy Key. With panoramic water views, a private beach, waterfront dock with a 20,000-pound boat lift, heated concrete pool, and lush tropical grounds, this property captures the very best of Florida Keys living. Surrounded by mature landscaping, the two-bedroom, two-bath residence enjoys a peaceful, private setting with beautiful Gulf views. Light-filled living spaces embrace the waterfront surroundings, while the kitchen features granite countertops and stainless steel appliances. Both bedrooms offer private baths for owners and guests alike. Step outside and the Keys lifestyle comes alive. Walk to your private sandy beach, lower the boat from your 20,000-pound lift for a day on the water, relax beside the heated pool, or watch the sun disappear over the Gulf from your own shoreline. Expansive grounds and tropical landscaping provide a level of space and privacy that can be difficult to find in the Keys. The property also boasts an exceptional rental history, consistently renting approximately 50 weeks per year and generating roughly $175,000 in annual rental revenue--a testament to the tremendous appeal of this waterfront setting. Whether you're searching for a private Keys retreat or a proven vacation rental investment, this Grassy Key property offers an extraordinary combination of lifestyle and opportunity. Private beach. Open Gulf views. Boating. Pool. Half an acre of tropical privacy. This is the Florida Keys lifestyle people dream about.
