About
Life in Seaford
Living in Seaford means choosing the practical middle ground of Long Island—a compact, family-oriented community where you're close enough to New York City to commute but far enough removed to actually afford a house with some stability. The median home value sits around $658,000 and median household income is $172,557, which reflects a solidly middle-to-upper-middle-class population that's largely made up of married couples with kids and people in their 40s and 50s who've settled in for the long haul. You're looking at a 38-minute average commute if you head into the city, and the LIRR Babylon Branch station makes that easier, though having a car is pretty much essential for day-to-day life here.
