Offered together as a rare package on the water in Hampton Bays, 298 and 300 East Montauk Highway combine for .66 acres and 3,975 square feet of living space across two homes. The waterfront main residence at 298 East Montauk Highway sits on .59 acres and delivers insane, unobstructed water views alongside 4 bedrooms, 4 bathrooms, a private hot tub, a spacious recreation room, and a garage, directly on the water's edge. The property also carries Southampton's RWB (Resort Waterfront Business) zoning designation, a rare classification reserved for the Town's most coveted maritime and resort corridors, the same zoning that anchors marinas, waterfront resorts, and hospitality destinations throughout Southampton's most desirable waterfront enclaves, lending the location real pedigree and long-term flexibility. Immediately adjacent, 300 East Montauk Highway rounds out the package on .07 acres with 3 bedrooms and 2 bathrooms, making it a versatile guest house, secondary residence, or income-generating companion to the main residence. Together, the two properties offer a rare chance to own a true waterfront compound in one of Hampton Bays' most sought-after corridors, directly across the street from The Hampton Maid, close to Cowfish, Canoe Place Inn, and Rumba, and less than five miles from Ponquogue Ocean Beach.
