About this home

Nestled in the heart of Seaview on an oversized 80' x 100' parcel, 6 Atlantic Avenue offers the rare combination of generous outdoor space, bay views, and a coveted location in one of Fire Island’s most beloved communities. This spacious four-bedroom, two-bath home is filled with natural light, featuring an expansive living room with bay window, generously sized bedrooms, and a bright, airy layout designed for effortless beach living. The enormous sun-drenched deck creates the perfect setting for outdoor dining, entertaining, or simply relaxing after a day at the beach. Mini-split heat and A/C provide modern comfort throughout the seasons. Ideally positioned in the quiet, highly desirable Seaview community—home to lifeguarded ocean and bay beaches, clay tennis courts, playground, kiddie pool, and a close-knit community atmosphere—yet just moments from the restaurants, shops, and energy of Ocean Beach. Whether you envision a classic Fire Island retreat, an investment property with strong rental appeal, or the site of your future dream home, this oversized property presents exceptional opportunity in a location that rarely disappoints. Flood insurance policy is assumable and costs $5,044/year.
