ZIP Code 02143

ZIP code 02143, in Cambridge, ranks among the more affluent corners of the Boston area, with a median household income of $130,753 and per-capita income of $80,068. Homes here carry a median value of $926,800, and the county-level effective property tax rate of 1.03% translates into a substantial annual bill at that price point. Sales tax runs 6.25% on purchases. High earnings and steep housing costs go hand in hand with that tax picture, so ownership here demands real income rather than offering any bargain.
