Property Description
Welcome to Key Lime Kottage, a charming waterfront retreat in Grassy Key where life slows down, the water calls, and every day feels like a Florida Keys escape. Currently in a vacation rental program, this turn-key 3-bedroom, 2-bath home offers buyers and investors the rare combination of personal enjoyment, rental potential, privacy, and resort-style living. Kindly provide at least 24 hours' notice for showings. Preferred showing times are Saturdays during check-in/check-out windows, when access is most convenient. Tucked behind lush tropical landscaping, Key Lime Kottage welcomes you with soft yellow cottage charm, a metal roof, white picket appeal, and a peaceful waterfront setting that immediately invites you to relax. From the moment guests arrive, they can imagine themselves slowing down, breathing deeper, and enjoying the Keys lifestyle. A beautiful composite dock leads through the mangroves toward open Gulf views, creating the perfect place for morning coffee, kayaking, paddleboarding, sunset conversations, or quiet moments by the water. The outdoor living area is the heart of the property. With a screened-in pool, spa, covered lounging space, and natural privacy, it feels like a private resort designed for relaxation, connection, and unforgettable memories. Inside, the open living, dining, and kitchen layout feels warm, easy, and welcoming. The home is ready for immediate enjoyment, whether as a personal retreat, a vacation rental investment, or both. For investors, Key Lime Kottage offers strong guest appeal with waterfront living, Gulf views, pool and spa amenities, and proximity to the Dolphin Research Center, The Wreck Restaurant, downtown Marathon, grocery shopping, marinas, entertainment, and MillionAir. Buyers are not just purchasing a property here. They are stepping into peaceful mornings, golden sunsets, waterfront memories, and a Florida Keys lifestyle guests will want to return to again and again.
