Interest Rates and Home Affordability: What's the Impact?

The relationship between interest rates and home affordability is one of the most misunderstood parts of the housing market, and the last twelve months proved it. The Federal Reserve cut its benchmark rate three times. Mortgage rates finished the period higher than they started.

If you have been waiting on the sidelines for the Fed to make homes cheaper, that is the single most important thing on this page. Let's look at what actually happened, why, and what it means for buying, selling, and investing in Massachusetts and New Hampshire right now.

What Actually Happened

We wrote the earlier version of this article in September 2025, when the market was pricing in a Fed cut and mortgage rates sat at 6.35%. The cut arrived. Two more followed.

The Federal Reserve, September through December 2025: three consecutive quarter-point cuts took the federal funds target from 4.25% to 4.50% down to 3.50% to 3.75%. The Fed has held there since, leaving rates unchanged at both its March and June 2026 meetings. The effective federal funds rate sat at 3.63% as of late August 2026.

Mortgage rates over the same period: they went the other way.

• Fed funds target: 4.00% to 4.25% in September 2025, now 3.50% to 3.75%. Down three quarters of a point.
• 30-year fixed mortgage: 6.35% then, 6.66% now. Up.
• 15-year fixed mortgage: 5.52% then, 5.98% now. Up.

Three quarters of a point of Fed cutting, and the 30-year mortgage is roughly a third of a point higher than it was a year ago, when it averaged 6.56%.

Why the Fed Cut and Mortgages Rose

This is the part that costs people money when they misunderstand it, so it is worth being precise.

The Fed does not set mortgage rates. It sets the federal funds rate, which is the overnight rate banks charge each other. That drives short-term borrowing: credit cards, home equity lines, auto loans, adjustable-rate products.

A 30-year mortgage is a long-term instrument. Its rate tracks the 10-year Treasury yield and the spread that mortgage investors demand on top of it. Those move on inflation expectations, government borrowing, and how much risk investors want to hold, not on what the Fed did last month.

So when the Fed cuts because it is worried about growth, and bond investors simultaneously decide that inflation will stay stickier than hoped, long rates can rise even as short rates fall. That is roughly what happened. Headline inflation is still 3.4%, above the Fed's 2% target, and shelter costs are the largest single reason why.

The practical lesson: waiting for a Fed announcement to time your mortgage is a strategy with no reliable connection to the thing you are trying to predict.

What Today's Rates Do to Your Budget

Here is the arithmetic on a real purchase, at today's rate.

A $500,000 home with 20% down, so a $400,000 loan:

• At 6.66% (today): monthly principal and interest of $2,571
• At 6.35% (a year ago): $2,489
• Difference: $82 a month, $979 a year, about $29,000 over the life of the loan

That is the cost of the year spent waiting for rates to fall, on this one house, before you count the rent paid in the meantime or the equity not built.

What You Need to Earn

Lenders generally want your housing payment under 28% of gross monthly income. Adding roughly $700 a month for taxes and insurance in this region:

• At 6.66%: you need about $140,000 of household income to qualify
• At 6.35%: about $137,000

The 15-year picture is different and worth a look if your budget allows it. At 5.98% a $400,000 loan costs $3,371 a month, far more than the 30-year, but you pay roughly $207,000 in total interest instead of about $525,000.

Where the Local Markets Stand

Massachusetts

As of June 2026, the state median sale price was $687,847, up just 1.2% from a year earlier. That deceleration matters: after years of high single-digit growth, prices are close to flat in real terms.

• Homes sold: 5,332 in June, up 3.2% year over year
• Homes for sale: 20,201, up 12.1% year over year
• Median days on market: 26
• Greater Boston median: roughly $857,000

The inventory number is the one to watch. Twelve percent more homes on the market is the most breathing room buyers have had in years, and it is why prices have stopped climbing quickly even though sales are up.

New Hampshire

As of May 2026, the median was $533,106, up 2.9% year over year, so New Hampshire is still appreciating faster than Massachusetts off a lower base.

• Homes sold: 1,590 in May, up 12.8% year over year
• Median days on market: 45
• Inventory: roughly 1.4 months of supply

That inventory figure is the story. A balanced market is 5 to 6 months. At 1.4, New Hampshire remains firmly a seller's market, which is why prices there keep rising while Massachusetts flattens. Sales volume up nearly 13% on that little supply tells you demand is not the constraint.

What This Means for You

If You Are Buying

The waiting strategy has now had a full year to prove itself and it did not work. Rates are higher, prices are higher, and a year of rent is gone.

What has genuinely improved is choice. Massachusetts has 12% more homes on the market than a year ago. More inventory means less bidding pressure, more room to negotiate, and a real chance to make an offer with inspection and financing contingencies intact rather than waiving your protections to win.

What to do:

1. Get pre-approved and understand your actual number, using 6.75% for planning rather than a hopeful figure
2. Ask about a rate buy-down. In a market with more inventory, sellers are more willing to pay points to close
3. Look at New Hampshire if you can work remotely. A $533,000 median against $688,000 is a real difference, and there is no state income or sales tax
4. Consider the 15-year loan if the payment fits. The interest saving is enormous

If You Are Selling

Massachusetts homes are still selling in 26 days, which is fast, but with 12% more competition on the market than last year, the days of listing anything and getting five offers are over in most price bands.

What to do:

1. Price to the comparable sales, not to what your neighbor got in 2024
2. Consider paying for a buyer's rate buy-down instead of cutting your price. It often costs less and moves the buyer's monthly payment more
3. Get the pre-listing work done. With more choice, buyers skip homes that need obvious attention
4. If you are also buying, remember you face the same rates on the other side, so time the two together

If You Are Investing

Higher long rates compress cash flow, and that has not changed. But the same rates keep would-be buyers renting, which supports rents.

New Hampshire's 1.4 months of inventory and 12.8% jump in sales point to genuine demand. Multi-family in the Merrimack Valley and southern New Hampshire still pencils out more often than single-family, and the rental side is being fed by the same affordability squeeze that is keeping people out of ownership.

Historical Perspective

Today's 6.66% feels punishing because of what came immediately before it, not because it is high by any longer measure.

• 1970s: 8% to 10%
• 1980s: 12% to 18%, peaking at 18.63% in 1981
• 1990s: 7% to 10%
• 2000s: 5% to 7%
• 2010s: 3% to 5%
• 2020 to 2021: 2% to 3%, the historic anomaly
• 2024 to 2026: 6% to 7%

The average since 1971 is just under 8%. We are below it. The 2% mortgages of 2021 were the aberration, not the baseline, and a generation of buyers formed their expectations during that window.

What to Expect Next

The Fed's own median projection points to about one cut in 2026, and it has held steady through two meetings this year. Even if that cut lands, the last twelve months are the evidence for what it will and will not do to a 30-year mortgage.

Inflation is heading the right way. Headline CPI eased to 3.4% in July from 3.5%, core to 2.5% from 2.6%, and shelter to 3.2% from 3.3%. Shelter posted its smallest monthly increase since January 2021. That trend, sustained, is what would actually bring long rates down, because it is what bond investors are pricing.

A realistic view: mortgage rates in the low-to-mid 6s through the rest of 2026, with meaningful improvement dependent on inflation continuing to cool rather than on any single Fed meeting.

Frequently asked questions

Does a Fed rate cut lower mortgage rates?

Not directly. The Fed sets the overnight federal funds rate, which moves short-term borrowing such as credit cards and home equity lines. A 30-year mortgage follows the 10-year Treasury yield and the spread investors demand on top of it. The Fed cut three times between September and December 2025, and the 30-year rate still rose from 6.35% to 6.66% by late August 2026.

Should I wait for rates to drop before buying?

The last year is the case against waiting on a forecast: rates rose while the Fed cut, prices edged up, and a year of rent was paid. If rates do fall after you buy, you can refinance, though that has costs of its own. Base the decision on your finances, how long you plan to stay, and the specific home.

What is a rate buy-down?

A payment, usually made at closing, that lowers the interest rate on the loan. A permanent buy-down pays points for a lower rate for the life of the loan. A temporary one, such as a 2-1 buy-down, lowers it for the first year or two. With more homes on the market, sellers are more willing to fund one, and it often moves the monthly payment more than an equivalent price cut.

Is a 15-year mortgage worth it?

If the payment fits, the saving is large. At 5.98%, a $400,000 loan costs $3,371 a month over 15 years, against $2,571 at 6.66% over 30, but total interest comes to roughly $207,000 instead of about $525,000. The tradeoff is less room in your monthly budget.

The Bottom Line

The past year is a clean natural experiment, and the result is unambiguous: the Fed cut three times and mortgage rates rose. Anyone who postponed a purchase waiting for the Fed paid rent for a year and now faces higher rates and higher prices.

That is not an argument to buy regardless of circumstances. It is an argument to make the decision on the things you can actually assess:

1. Your finances, not a rate forecast
2. The total cost of ownership, not the monthly payment alone
3. How long you plan to stay. Under five years, the transaction costs are hard to overcome at any rate
4. The specific property, because the right house at 6.66% beats the wrong house at 5.5%

Massachusetts and New Hampshire remain fundamentally strong: diverse employment, good schools, constrained land supply. Massachusetts buyers have the most choice they have had in years. New Hampshire buyers face tighter supply but lower prices and no income or sales tax.
