About this House

Set on a rare corner waterfront lot in the heart of Boot Key Harbor, this tropical retreat blends island charm with modern comfort and effortless boating access with ample parking for both boat trailers and vehicles. With direct ocean access and deep sailboat-friendly waters, this two-bedroom home is your gateway to the ultimate Keys lifestyle—morning coffee on the dock, afternoon snorkeling runs, and sunset cocktails under the tiki. Sold fully furnished and rental-ready, it's perfect as a lucrative vacation rental or a private escape. Inside, warm cedar accents and pine siding bring a cozy coastal feel, balanced by modern upgrades like smart TVs, ceiling fans, and a Ring security system. The kitchen is built for serious cooking, featuring a propane stove, vented microwave, and refrigerator with ice maker, while the large laundry room—with brand-new washer and indoor/outdoor access—adds convenience. Even the half bath carries local flair with its ship's porthole mirror nodding to Keys nautical heritage. Outside, tropical landscaping sets the stage for fun and relaxation. Banana trees sway beside manicured planters with a water system. The tiki hut complete with a black granite bar top, fan, and string twinkle lights invites entertaining at any hour. Grill your fresh catch, rinse off in the outdoor shower, or gather at the 65-ft concrete dock to watch the harbor lights shimmer. Boaters will love the 8,000-lb lift with new Gem control box, extended courtesy dock, stainless fish-cleaning station, bait freezer, and even an antique ship's bell to mark the day's end.
With quick, deep-water access to both the Atlantic and Gulf, this home captures everything that makes Keys living unforgettable boating, sunsets, and a relaxed sense of adventure. Whether you're looking to generate income or anchor your island lifestyle, this Boot Key Harbor gem is ready to welcome you home. Financing is available through local lending institute.
