How it works
Buying a median-priced home in Boston. At $760,000 with a 20% down payment, you'd bring $152,000 to closing (plus closing costs) and take out a $608,000 mortgage. At a 6.50% interest rate on a 30-year fixed loan, your monthly principal + interest is roughly $3,843.
Annual costs on top of the loan. Massachusetts's average property tax rate is 1.23%, so a median-priced Boston home generates approximately $9,348 in annual property tax (about $779/mo when paid through escrow). Homeowner's insurance in Massachusetts averages around $1,500/year.
Total monthly payment (PITI) on the median Boston home works out to about $4,747 per month at current rates, assuming a 20% down payment and no HOA. If you're putting less than 20% down, add PMI to this — typically 0.5–1.5% of the loan balance per year.
Rates change; this is the math, not the offer. Mortgage rates fluctuate daily. Our default of 6.50% is a recent conventional 30-year benchmark — enter today's quoted rate from your lender for the most accurate payment estimate.
