Mortgage rates rose again this week, marking the seventh consecutive week. For anyone shopping for a new home, Massachusetts mortgage rates are at their highest in almost three years. Here is what changed and what to do.


Mortgage Rates at 7.4%: What It Adds Monthly
Mortgage Rates at 7.4%: What It Adds Monthly

What happened this week


Freddie Mac said the average 30-year fixed rate was 7.40% on October 8. That is up from 7.28% a week ago. A year ago it was 6.30%. The 15-year rate rose to 6.73%.


The Associated Press reports this is the highest rate since November 2023. In late February, the rate dipped to 5.98%. Since then, it has climbed 1.42 points. The AP says that adds about $376 a month on a $400,000 loan.


Mortgage rates follow the 10-year Treasury bond. The AP says that yield hit 5.29% on Thursday, its highest since 2002. A Realtor.com economist told Fox Business that high rates "have the housing market spooked."


Buyers are pulling back. The Mortgage Bankers Association said purchase loan applications were 14% lower than in late September a year earlier.


Massachusetts mortgage rates and your payment: U.S. vs. MA vs. Middlesex County


Here is my math. It uses 20% down and principal and interest only. Taxes, insurance, and HOA fees are extra. It compares this week's 7.40% rate with last year's 6.30%.


  • U.S. new home: The Census Bureau's August median new home price was $393,700. The payment goes from about $1,950 to $2,181. That is $231 more a month.

  • Greater Boston: The Boston Globe put the median Greater Boston home at $852,500 in February. The payment goes from about $4,221 to $4,722. That is $501 more a month.

  • Middlesex County new homes: My MLS PIN search of single-family homes built in 2026 that sold in the past six months found a median price of $1,790,000. The payment goes from about $8,864 to $9,915. That is $1,051 more a month.


Another way to see it is that the same monthly payment now buys about 10.6% less loan than a year ago (my math). For a Middlesex new-home buyer, that is roughly $152,000 less house.


The Globe also reports that a typical Greater Boston purchase now costs about $1,000 more a month because of higher rates.


The jumbo loan factor


A "jumbo" loan is a mortgage larger than the limit Fannie Mae and Freddie Mac will buy. Banker & Tradesman reports the 2026 limit is $832,750 in most of the country and $962,550 in the five Greater Boston counties.


That matters here. With 20% down, the $1,790,000 Middlesex median means a loan of about $1,432,000. That is $469,000 over the local limit (my math). So most new-home buyers in towns like Lexington, Newton, Winchester, or Concord are jumbo borrowers.


Jumbo rates are not always higher. The MBA said its average 30-year jumbo rate was 7.27% in late September, slightly below its 7.30% rate for regular loans. But jumbo loans often require more cash down, more savings, and stronger credit. I couldn't find a jumbo rate specific to Middlesex.


A split market


The Globe reports that homes in Greater Boston priced above $3 million to $4 million are still selling fast. It says middle-income buyers are the ones being squeezed.


My MLS PIN data fits this. Middlesex new homes built in 2026 went under agreement in a median of 12 days and sold for about 98% of the asking price. Most of those deals were signed before rates passed 7%. Things will likely slow this fall.


Builders are offering deals


NAHB said 66% of builders used sales incentives in September. 38% cut prices by an average of 6%. A Realtor.com study, as reported by The Close, found 13.8% of new-home listings advertised a lower mortgage rate in August.


A "buydown" is when the builder pays the lender to lower your rate. It can be for the first year or two or for the whole loan. Big national builders do this most. Small local builders in the Boston suburbs are more likely to bargain on price, upgrades, or closing costs. That is my experience, not a survey.


What should buyers do?


  • Get pre-approved again. If your approval is from summer, your budget may have shrunk about 10%.

  • Ask about jumbo rules early. Over $962,550? Ask your lender how much cash and savings you need.

  • Ask the builder for a deal in writing. Compare a rate buydown with a price cut. A price cut lowers your payment for good. A short buydown only helps for a year or two.

  • Lock smart. New homes take months to finish. Ask about a long rate lock and a "float-down," which lets your rate drop if the market drops.

  • Don't wait for a perfect rate. The Boston Fed's Paul Willen told the Globe there's "no logical reason why 7 is any different from 6 percent." Buy when the home and the payment fit.
