Compare 15-year and 30-year mortgage options for Massachusetts homes. See the monthly payment difference and total interest savings on the $595K median home.
The choice between a 15-year and 30-year mortgage in Massachusetts comes down to monthly cash flow versus total cost. On the $595K median home with 10% down, a 30-year mortgage at 6.5% gives you a total PITI of $4,163/mo. A 15-year mortgage at 6.0% (15-year rates are typically 0.5-0.75% lower) pushes that to $5,297/mo — about $1,134 more per month. But you save approximately $405K in total interest and own the home free and clear in half the time.
In Massachusetts's higher-cost market, the monthly difference between 15 and 30 years is substantial: $1,134 per month. That is a significant commitment for many Massachusetts households, especially first-time buyers already stretching to afford the down payment and closing costs. The 30-year mortgage often makes more practical sense here, preserving monthly flexibility while still building equity. If your income grows over time, you can always make extra principal payments on a 30-year loan to capture some of the interest savings without being locked into the higher payment.
Whichever term you choose, the MassHousing DPA program (up to $50,000 dpa loan) can ease the upfront burden.

Common Questions
Is a 15-year mortgage worth it in Massachusetts?+
A 15-year mortgage on the Massachusetts median home saves approximately $405K in total interest compared to a 30-year term, but the monthly PITI jumps from $4,163 to $5,297 — an increase of $1,134/mo. It is worth it if you can comfortably afford the higher payment while still saving for retirement and maintaining an emergency fund. If the higher payment would strain your budget, the 30-year term with occasional extra payments is a safer approach.
What is the rate difference between 15 and 30 year mortgages?+
15-year mortgage rates are typically 0.5% to 0.75% lower than 30-year rates. As of 2026, if 30-year rates are near 6.5%, 15-year rates would be approximately 5.75%-6.0%. This rate advantage compounds the savings: you pay less interest per dollar borrowed AND you borrow for half as long. On the $595K Massachusetts median home, this combination produces savings of roughly $405K over the life of the loan.
Can I refinance from a 30-year to a 15-year mortgage in Massachusetts?+
Yes. If rates drop or your income increases after purchase, refinancing from a 30-year to a 15-year mortgage is a common strategy. Closing costs for a refinance in Massachusetts typically run 1-2% of the loan balance. The breakeven on those costs is usually 2-3 years, so it makes sense if you plan to stay in the home at least that long. Alternatively, you can simply make extra payments on your 30-year loan to achieve a similar effect without paying refinance fees.
