Massachusetts Mortgage Calculator
This planning example uses a $607,400 home value—the 2024 ACS median for owner-occupied homes in Massachusetts—with 20% down and a 30-year fixed mortgage. The rate is the Freddie Mac national weekly average as of July 9, 2026; it is not a Massachusetts rate, a personal quote or an offer to lend. Customize the inputs with a property-specific tax bill, insurance quote and lender rate.
State planning scenario
$607,400
$3,731
| Down payment (20%) | $121,480 |
|---|---|
| Mortgage principal | $485,920 |
| 30-year fixed rate | 6.49% |
| Principal & interest | $3,068.15/month |
| Property tax | $506.67/month |
| Homeowners insurance | $155.92/month |
| PMI | $0.00/month |
| HOA dues | $0.00/month |
| Estimated total | $3,730.74/month |
PMI is $0 in this example because the starting loan-to-value ratio is 80%. Change the down payment in the calculator to model a higher LTV. HOA dues default to $0 because there is no reliable statewide amount.
What is localized for Massachusetts?
| Median owner-occupied home value | $607,400 (ACS 2024) |
|---|---|
| Property-tax planning proxy | 1.00% (ACS 2024) |
| Annual HO-3 insurance average | $1,871 (NAIC 2022) |
The tax percentage is median annual real-estate taxes paid divided by median home value. It is a ratio of statewide medians—not a statutory rate or a parcel-level effective rate. The insurance figure is a historical statewide average across policies and coverage amounts, not a current quote. Flood, earthquake, wind or other separate coverage may not be included.
