Description
Welcome to your private slice of the Florida Keys lifestyle, where boating days, poolside afternoons, and sunset dinners by the water become part of everyday life. Ideally positioned on a deep-water canal in the heart of Marathon, this beautifully maintained 4 bedroom, 3 bathroom waterfront home blends relaxed island living with comfort, space, and functionality. Inside, the spacious layout is filled with natural light and designed for gathering and entertaining. The open living areas flow effortlessly into the dining space and kitchen, creating a warm and inviting atmosphere for family and guests. Just off the dining area, a dedicated bar area provides the perfect space for serving drinks and entertaining after a day on the water. The large primary suite serves as a peaceful retreat, featuring a generous bedroom and private en-suite bath, while the additional guest bedrooms are thoughtfully arranged to provide comfort and privacy. Well-appointed bathrooms throughout complement the home's relaxed coastal aesthetic. Step outside and the Keys lifestyle truly unfolds. The backyard is designed for relaxation and entertaining, highlighted by a private pool, a tiki hut for shaded outdoor dining, and a waterfront setting that invites you to slow down and enjoy island living. The full concrete dock is equipped with a 16,000 lb boat lift and sits on deep draft water with quick boating access to both the Atlantic and Gulf. An established vacation rental, the property offers flexibility for buyers seeking a strong investment opportunity, a 2nd home getaway, or a full-time residence. The attached garage provides valuable storage for all your toys and offers potential for conversion into a 5th bedroom or laundry room if additional space is desired. Located in the heart of Marathon, the home is just minutes from Marathon Airport, making travel to and from the Keys a breeze, while placing restaurants, bars, beaches, shopping, and nearby state parks all within easy reach.
