Luxury Waterfront Estate & Premier Vacation Investment - Marathon, FL Introducing The SaltyLime, a rare new-construction waterfront estate completed in 2024 and designed to deliver both tropical elegance and outstanding rental performance. This fully turnkey 6-bedroom, 6-bath property blends the relaxed lifestyle of the Florida Keys with resort-style amenities and seamless indoor-outdoor living. The main house features three spacious king suites and a custom nautical themed bunk room, while two detached bungalows each offer private king suites with individual climate control, creating accommodations for up to 14 guests. Every detail has been thoughtfully designed, from the professionally styled interiors to the island-inspired kitchen with a bar area for entertaining. Outside, expansive living spaces include a heated and cooled saltwater pool and spa, a two-story tiki deck, expansive outdoor living area, and 90 feet of deep-water dockage with slips for up to four boats. As an investment, The SaltyLime has proven itself from the start, generating 32 weeks booked and more than $235,000 in its first year and has already secured over $280,000 in current and future reservations, all supported by a flawless 5-star guest review record across all platforms. The estate comes fully furnished and rental-ready, complete with branding and website, décor, future bookings and systems already in place, making it an effortless transition for new owners. Perfectly suited for boaters, anglers, and families alike, this property is more than a vacation home-it's a high-performing asset and a slice of Keys paradise ready to be enjoyed
