Property description

2BD/2BA waterfront half-duplex in Key Colony Beach, offering impressive water views from both the front and back of the home. Stilted concrete construction, metal roof and impact windows make the insurances extremely affordable. Wake up to glowing sunrises over the water and wind down with color-soaked Keys sunsets from your private balconies perfect for morning coffee, sunset cocktails, and effortless indoor-outdoor living. A deep-water pier-style dock accommodates boats up to 40 ft giving you instant access to world-class fishing, diving, and boating. Designed for adventure and convenience, the property includes parking for up to 3 vehicles, 2 covered spaces beneath the home and an additional uncovered driveway space ideal for extra parking or a boat trailer. A dedicated tackle room keeps gear organized and ready for your next trip offshore. Everything you love about Key Colony Beach is within easy walking distance, Sunset Park for oceanfront strolls and nightly sunsets, the Key Colony Beach Golf Course, tennis and pickleball courts, the Cabana Club with oceanfront pool and beach access (membership-based), and the Key Colony Beach Marina. Restaurants, walking paths, and the island's friendly, laid-back atmosphere are all right at your doorstep. With 7-day rentals permitted, this property offers excellent vacation-rental potential in one of the most desirable waterfront, boating communities in the Middle Keys. A bright, breezy coastal escape and always a pleasure to show.
