Mortgage Rates Hit 7.40%: What Does It Really Cost to Buy a Home on Boston's North Shore?

On October 8, Freddie Mac reported a national average 30-year fixed mortgage rate of 7.40%, up from 6.30% one year earlier.

In plain terms, this is the national average 30-year fixed rate as of October 8, 2026, and it is up more than a full point from a year ago. The national average matters because it moves the payments that decide whether a home is affordable. On the North Shore, where the median single-family home is around $860,000, even a small rate change shifts the monthly number by hundreds of dollars.

These figures are principal and interest only, before property taxes, homeowners insurance, and, on the coast, flood insurance, all of which add real money in Massachusetts. Start with a home around $700,000 with 20 percent down, a $560,000 loan.

At 6.30%, the principal and interest payment is roughly $3,470 a month. At 7.40%, it is roughly $3,880 a month, about $410 more each month. Over 30 years, that difference adds roughly $148,000 in interest. That is the real cost of a single point: it is not a small rounding error, it is a meaningful part of the monthly budget and the long-term total.

A higher rate does not just raise the payment; it shrinks what you can borrow. To keep the same $3,470 monthly payment at today's 7.40%, a buyer would need to borrow about $500,500 instead of $560,000, which at 20 percent down means a home around $625,000 instead of $700,000.

That is roughly $75,000 less buying power from one year's rate move, on the same monthly budget. It is why the rate conversation has to come before the house tour: the payment decides the price range, and the rate decides the payment.

Now put the math on the North Shore. With the regional single-family median around $860,000, the principal and interest payment on a 20 percent down purchase runs roughly $4,760 a month, before taxes, insurance, and flood insurance.

Add Massachusetts property taxes and homeowners insurance, plus flood insurance in many coastal towns, and the real monthly cost for the median home lands well above $5,000 a month in many towns. That is the number buyers are planning around, and it is the number that makes pricing, condition, and presentation matter more for sellers.

Start with preapproval, so you know your true monthly budget at today's rate before you look. A lender runs your real numbers, including taxes and insurance, and the payment tells you the price range you can actually carry. Buyers who get preapproved early can move when the right home appears.

Consider the options with professional advice: adjustable-rate mortgages and rate buy-downs can lower the starting payment, but they carry trade-offs worth understanding. And remember that refinancing later is an option, so today's purchase is not a lifetime rate lock. If rates fall, many buyers refinance and lower that payment.

Higher rates make buyers payment-sensitive, which means pricing, condition, and presentation matter more than ever. A well-priced home still sells, because households still need to move for jobs, space, downsizing, and lifestyle changes. But buyers are doing the math, and a home that shows well and is priced to the current market will win the attention.

The market has not stopped; it has gotten more deliberate. Sellers who price to today's comparables and present their home well are the ones who sell, and often sell well. The strategy from my pricing guide applies here: at or slightly under market, a strong first two weeks, and a home that shows beautifully.
