About This Home

230 Sadowski Causeway

Your dream Florida Keys waterfront escape starts here--built for boaters who need extra space! Built in 2023, this sleek 3-bedroom, 3-bath residence features a rare 49-foot concrete dock, standing far above the island's standard 30-37.5-foot dockage allowance to accommodate larger vessels with ease. Inside, enjoy airy 9-foot ceilings, crisp tile floors, a stunning white-and-quartz kitchen, and an oversized 2-car garage for gear. Spend afternoons relaxing by the pool or running out to your favorite fishing spot. Perfectly set up as a high-performing weekly vacation rental with proven bookings, this property also offers the rare chance to acquire the adjacent half duplex (232 Sadowski) to double your rental footprint or create an extended family estate. Located in the resort community of Key Colony Beach with restaurants, 9-hole golf course, Sunset Park, sports courts and shopping, all within walking or biking distance.
