ZIP Code 01730

Households in ZIP code 01730, near Cambridge, report a median income of $172,400, with per-capita earnings of $93,430. A median home value of $898,500 paired with a 1.03% county property tax rate means annual property taxes land near $9,255, a meaningful line item even at these income levels. Sales taxes add 6.25% to most purchases. High earnings here support substantial housing costs, but the property tax bill still claims a noticeable share of annual income, so owners should plan for that recurring expense alongside their mortgage.
