ZIP Code 11727

ZIP code 11727, centered on Stony Brook, sits comfortably in the affluent tier: a median household income of $103,287 and per-capita income of $49,320 place it well above national norms, while a median home value of $443,200 reflects a high-cost housing market. That value carries a county-level effective property tax rate of 1.73%, a substantial annual obligation. Add an 8.75% combined sales tax, and the overall tax load here runs high, though the income base supports it. This is an upper-middle to affluent area where earnings and housing costs move together.
