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.

Description

Waterfront Investment Opportunity in the Florida Keys! Located in desirable Key Colony Beach, this 3-bedroom, 2-bath property offers the perfect blend of tropical living and income-producing potential. Built in 2006, and 'above flood' this popular ''Ellison'' half duplex offers 1,540 sq ft of well-designed living space on one level with NO STAIRS to climb. Offering more dockage than most half duplexes, with 46 FEET OF CANAL FRONTAGE WITH STEP DOWN DOCK and quick access to the ocean--a dream setup for boating, fishing, and watersports enthusiasts. This property has operated as a well-established and successful weekly vacation rental for over 10 years. Per the seller, it generates, on average, $135K-$140K in annual gross income and rents 49 weeks per year. Future bookings are strong, making this a truly turnkey investment opportunity. Inside, you'll find a bright and open floor plan with tile flooring throughout, complemented by a nice sized kitchen with granite countertops, stainless steel appliances, and ample cabinet space. The spacious primary suite includes an ensuite bath with double vanities, while two additional bedrooms offer flexibility for guests or family. Step outside and enjoy true Florida Keys outdoor living with your private pool, the perfect spot for relaxing after a day on the water, and there's plenty of room in the TWO-CAR GARAGE to store your boating and fishing gear. You'll also enjoy access to all that Key Colony Beach has to offer, including Sunset Park, tennis courts, pickleball, a 9-hole golf course, playground, and a couple of restaurants--all within easy walking or biking distance. Whether you're seeking a second home in paradise or a proven short-term weekly rental, this property delivers both lifestyle and ROI. Enjoy it yourself when you like, and have it generate income for you when you can't be there!
