How much is a monthly mortgage payment in Massachusetts?
Here's a worked example for Massachusetts. On a $400,000 home with 20% down ($80,000), you'd borrow $320,000. At a 6.55% 30-year fixed rate — the current U.S. national average — the principal and interest come to about $2,033 per month. Adding Massachusetts's average effective property tax of 1% ($4,000 a year, or $333 a month) brings the core housing cost to roughly $2,366 per month, before home insurance and any HOA dues. Enter your own price, down payment, and rate in the calculator above to get your exact number.

Conforming loan limits in Massachusetts — when you cross into jumbo
Limits are set county by county, not state by state. For 2026 the national baseline is $832,750; above your county's limit you're into jumbo territory.
Massachusetts is a state where this genuinely varies: 7 of its 14 counties carry a high-cost limit above the $832,750 baseline, topping out at $1,249,125. The rest of the state sits at the baseline. That means two buyers in Massachusetts borrowing identical amounts can land on opposite sides of the jumbo line depending only on which county the property is in — worth checking before you assume your rate.
| County | 2026 one-unit limit |
|---|---|
| Dukes County | $1,249,125 |
| Nantucket County | $1,249,125 |
| Essex County | $962,550 |
| Middlesex County | $962,550 |
| Norfolk County | $962,550 |
