An extraordinary Seaford waterfront estate — impeccably renovated and turnkey — offering 5 bedrooms plus an office, 4 full baths, a 40' floating dock, an 86' bulkhead (elevated ~3' in 2021) and a private boat slip. This is a possible mother-daughter with permits. Meticulously upgraded within the past five years, the home features new plumbing and electrical systems and 2022 windows, an ~11-year roof, and a Navien tankless water heater. Culinary and comfort amenities include gas cooking, a natural gas BBQ hookup, pot fillers in both kitchens and an upstairs instant-hot filler, a gas fireplace, and electric mini-split climate control with individual heat units. Luxurious finishes and thoughtful systems—heated bathroom floors (two upstairs and the main first-floor bath), electric bathroom heat, soundproofed underlay on all floors, regular and blackout shades, closets with auto on/off lighting, and a double-flap dog door—combine with practical, future-ready infrastructure: spray-foam insulated crawl space with lights and outlets, PVC conduit from attic to crawl space for wiring runs, full standing attic access, and crawl-space entry in the upstairs hallway closet. Owner-focused conveniences include a laundry chute, garage sink with hot/cold water and sprinkler controls, IG sprinklers installed within two years. Flood insurance is required. This premier waterfront residence delivers modern systems, elevated comfort and unparalleled water access — a refined sanctuary for boating, entertaining and everyday luxury.
