About

Life in Selden

This sprawling suburban hamlet on Long Island sits squarely in the middle-class sweet spot—stable, family-oriented, and surprisingly affordable for the New York area. With a median household income around $109,000 and median home values in the mid-$462k range, you're getting suburban space without Manhattan prices, though you'll need a car because this is decidedly car-dependent suburban living. The job market is solid with unemployment hovering near 3.4%, well below the national average, and you've got Suffolk County Community College's Ammerman Campus right there if you need flexible educational options.
