No canal width is published for this dock — we found no facing bank within canal range to measure against.

That is the absence of a measurement, not a finding of open-water frontage. Check the waterway, depth and slip dimensions with the listing agent.

Description

From the moment you arrive, this charming waterfront cottage invites you to leave the outside world behind. Tucked among lush tropical landscaping, its soft yellow exterior, metal roof, and classic white-picket charm set the mood for something unforgettable. Welcome to Key Lime Kottage, a turnkey 3-bedroom, 2-bath waterfront retreat in Grassy Key, where time slows, conversations last longer, and every day feels like a Florida Keys vacation. Inside, the open living, dining, and kitchen areas flow effortlessly, creating a warm setting for relaxed meals and time together. Outside, Key Lime Kottage becomes your secluded resort. The screened-in pool and spa, covered lounging area, and tropical privacy invite you to unwind. Imagine floating beneath the sun, relaxing in the spa, and sharing a toast as the sky turns gold and coral. A composite dock leads through the mangroves toward open Gulf views. Begin the morning with coffee by the water, launch a kayak or paddleboard, or sit together and enjoy the soothing rhythm of the Keys. Currently in a vacation-rental program, Key Lime Kottage combines personal enjoyment with income-producing potential. Its waterfront setting, open-water views, pool, spa, privacy, and turnkey condition create the resort experience guests seek--and want to revisit year after year. Conveniently located near the Dolphin Research Center, The Wreck Restaurant, downtown Marathon, shopping, marinas, and Million Air, the home feels private yet connected. You are not simply purchasing a property. You are investing in peaceful mornings, poolside afternoons, romantic sunsets, and a Florida Keys lifestyle guests will remember long after leaving. Could Key Lime Kottage become your private escape, income-producing retreat--or both? Kindly provide at least 24 hours' notice for showings. Saturdays during guest check-in and check-out windows are preferred.

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
