Mortgage Rates Top 7%: Boston Buyers Just Gained Leverage

Last week one of my buyers got a rate quote of 7.125% on a 30 year fixed. A year ago the same client would have been looking at something closer to 6.3%. Their first reaction was the one I hear every time rates jump: maybe we should wait.

I understand the instinct. I also think it is usually backwards. When rates spike, a lot of buyers step back at the same moment, and the ones who stay in the market stop competing against a crowd. The price you negotiate is permanent. The rate is not. That is the whole idea behind the phrase you have probably heard from agents and lenders: marry the house, date the rate.

I did not want to write this on instinct alone, so we tested it. We lined up 50,622 single family contracts across 32 Greater Boston communities from our MLS PIN feed, going back to 2019, against Freddie Mac’s weekly rate history. The short version is that rate spikes really do take the air out of bidding wars here, the effect is measurable in dollars, and it does not last long. The longer version, with the math and the risks, is below.

Where rates actually are this week

Freddie Mac’s Primary Mortgage Market Survey put the 30 year fixed at 7.03% on September 24, 2026. That was the fifth straight weekly increase and the first reading above 7% since January 2025, about 20 months (NPR). The path was 6.65% on August 20, 6.71% on September 3, 6.76% on September 10, 6.95% on September 17, then 7.03%. The 15 year fixed is at 6.42%.

Freddie Mac’s number is a weekly average for well qualified borrowers, and it lags. Other measures run higher. The Mortgage Bankers Association’s weekly survey had the 30 year conforming rate at 7.12% with 0.73 points for the week ending September 18, the highest since May 2024. Mortgage News Daily’s daily index, which moves with the bond market in real time, was at 7.50% on September 28.

So my client’s 7.125% was a fair quote. It sits right on the MBA average. Lenders price in eighths of a point, and whether a given quote is good depends on the points and credits attached to it, so compare the full Loan Estimate, not the headline rate.

Why rates jumped this month

Mortgage rates follow the 10 year Treasury more than they follow the Fed, and the 10 year has had a rough September. It crossed 5% on September 15 for the first time since 2007 and closed at 5.24% on September 28, two basis points under its 2007 peak (24/7 Wall St).

The drivers are inflation and energy. August CPI came in at 3.4% year over year, with energy up 16.3% and gasoline up 27.4% (BLS). On September 16 the Federal Reserve raised its target range by a quarter point to 3.75% to 4.00%, its first hike in more than three years, and its own projections show PCE inflation at 3.7% for 2026 (Federal Reserve). Rates were near 6% in late February, when Freddie Mac recorded a 5.98% low. They have climbed roughly a full point since.

I am not going to predict where they go next. Neither Fannie Mae nor the MBA expects a quick drop. Both forecast the 30 year near 6.7% to 6.8% through 2027 (Fannie Mae ESR, Sept 11; National Mortgage News), and Fannie’s forecast was built on August 31 rates, before this spike. Keep that in mind later, when we get to refinancing.

Buyers are already pulling back

The demand side reacted within weeks. MBA purchase applications went from up 0.2% year over year in mid July to down 19% for the week ending September 11 and down 11% for the week ending September 18 (HousingWire). Redfin reported that pending sales nationally fell to their lowest level in nearly three years in the four weeks ending September 13, down 5.4% from a year earlier, and Google searches for “homes for sale” were down 15% (Redfin).

Meanwhile supply here is rising. Redfin counted Boston metro active listings up 18.7% year over year in August, the second largest increase of any major metro (Redfin Market Tracker). The Greater Boston Association of Realtors reported single family new listings up 31.3% in August (GBAR). Inventory measures disagree with each other, Zillow actually shows Boston inventory down 4.2%, but the direction in the MLS data we see every day is more listings and fewer buyers per listing.

The psychology is easy to see in the surveys. Bright MLS chief economist Lisa Sturtevant told the Boston Globe that 7% creates “a psychological and financial barrier.” A Neighbors Bank survey found more than half of would be buyers are waiting for rates near 5% (Newsweek). A rate that starts with a 7 is not much more expensive than one that starts with a 6.9, but it feels different, and that feeling is what clears the field.

What our data shows about rates and bidding wars

Here is the part I most wanted to test. For every month from 2019 through July 2026 we took single family homes that went under contract in 32 Greater Boston communities, from Boston and Cambridge out to Framingham, Woburn and Braintree, and measured what share sold above the list price and what they sold for as a percent of the original asking price. Then we compared each month to Freddie Mac’s average rate that month. We grouped by the month the contract was signed, not the month it closed, because the rate that shapes an offer is the rate on the day you write it.

Two findings came out of it.

The level of rates barely matters on its own. The correlation between the rate that month and how hard buyers bid was weak, about minus 0.13. That makes sense in Greater Boston. In the spring of 2024, rates were near 7% and buyers were still paying 104% of the original list price, because there was almost nothing for sale. People adjust to a level.

What matters is the change. When we compared each month to the same month a year earlier, the relationship was much stronger, a correlation of about minus 0.51. The months where rates had risen a full point or more over the prior year stand out clearly.

Look at the second row from the bottom. When rates rose modestly, a quarter point to a point, competition actually went up. Some of that is buyers rushing to lock before rates climbed further, which we also saw in the spring of 2022. The cooling shows up once the increase is large and has held for a while. In those months the share of homes selling over list dropped 8.6 points versus the prior year, and the typical sale came in 2.1 points lower relative to the original asking price.

On a $900,000 house, 2.1 points is about $19,000. And that is the average across every month in the group. At the sharpest point, the gap was more than twice that.

What happened in 2022, month by month

The cleanest test is the 2022 run from about 3% to about 7%. Here is what Greater Boston single family buyers paid, as a percent of the original list price, by the month they signed the contract.

The seasonal pattern is real, fall is always softer than spring, so the fair comparison is the same months a year apart. Contracts signed from September through November 2021, with rates near 3.0%, closed at an average of 102.1% of the original list price, and 61.5% of them sold over list. The same months in 2022, with rates averaging 6.6%, closed at 97.8%, and only 43.8% sold over list. For October through December the drop was even larger, 101.7% down to 96.8%, and the over list share fell from 58.1% to 38.1%.

That is roughly five points of price on the same kind of house in the same towns. Redfin’s bidding war tracking tells the same story from a different angle. In March 2022, 79% of Boston area offers faced competition. By August 2022 it was 54% (Redfin).

Now look at the last two bars. By the spring of 2023, rates were still around 6.5%, and buyers were back to paying 103% to 105% of list. Median prices here never really fell. GBAR reported a record July 2023 single family median of $910,000 even as sales dropped 23.4% (GBAR). In a supply constrained market like ours, high rates cut the number of sales far more than they cut prices. The discount lives in the negotiation, and it lives in the first few months after the spike, before buyers get used to the new number.

What I am seeing right now

Contracts signed this September have not closed yet, so the closed data cannot show this spike. The August numbers still look firm on paper. GBAR’s August single family median was $1,002,500, up 6.6%, and sellers received 99.7% of original list, the same as a year ago. Those deals were written in July and August with rates in the mid 6s.

The live listings tell you where it is heading. As of this week, 38.1% of active single family listings in these 32 communities have already taken at least one price cut, with a median cut of 5.0%. Across Massachusetts, price reductions in August were up 47.8% year over year, according to Warren Group data reported by Lamacchia Realty. GBAR president Joselin Malkhasian has said to expect “less buyer competition in the fall months” (Banker & Tradesman).

On the ground that shows up as fewer offer deadlines, more houses reaching their second weekend, and more sellers willing to talk about inspection terms and closing credits they would not have discussed in May. In towns like Arlington and Newton, where spring buyers routinely waived contingencies, I expect this fall to look a lot more like the fall of 2022 than the fall of 2025.

The math: two buyers, one house

Here is a worked example using numbers from our own data. Same house, listed at $900,000. Both buyers put 20% down on a 30 year fixed, so the loan stays under the $962,550 conforming limit for Middlesex, Suffolk and Norfolk counties.

Buyer A buys this fall at 7.125% and, like the average buyer in a spike, pays 97.8% of list. Buyer B waits for a calmer rate environment, gets 6.125%, and pays 102.1% of list because the competition came back with the lower rate. Those two percentages are the actual fall 2022 and fall 2021 averages from our data.

Buyer A starts out paying $277 a month more. Over two years that is about $6,650. In exchange, Buyer A paid $38,700 less for the same house, needed $7,740 less cash at closing, and owes about $27,000 less on the mortgage after two years.

If rates come back to 6.125% and Buyer A refinances, paying an assumed 2% of the balance in closing costs, about $13,800, the new payment is $4,191. That is $276 a month less than Buyer B, for the rest of the loan. The refinance saves $553 a month against the old payment, so it pays for itself in about 25 months.

I am showing both sides on purpose. The strategy is a bet that rates come back down at some point in the years you own the home. The lower price is your protection if they do not. It shrinks the loss, but it does not erase it.

Where “date the rate” goes wrong

The phrase has critics, and they have a point. Nicole Rueth of CrossCountry Mortgage told Bankrate she is “not a fan” of it and has never been, and noted that rates may not return to past levels (Bankrate). The same piece cited a Truework survey in which 56% of recent buyers said they were counting on lower rates. NAR’s own magazine ran a piece in 2025 asking whether it was time to retire the phrase (NAR).

Here is where I think it breaks down, and how I handle each with clients:

1. You have to afford today’s payment. If the payment at 7.125% only works once you refinance, you cannot afford the house. I want clients comfortable at the rate on their Loan Estimate, with room left for taxes, insurance and repairs.
2. A refinance is not free. Freddie Mac says to expect 3% to 6% of the loan principal. LodeStar’s 2025 data puts the national average much lower, about 0.72% of the loan before points. Our example assumed 2%. Get a real quote from your lender, because the answer changes the break even.
3. The drop has to be big enough. The standard academic work on this, by Agarwal, Driscoll and Laibson, puts the rate drop that justifies refinancing at about 1.07 points on a $1 million loan and 1.18 points on $500,000. A quarter point dip does not do it.
4. You have to qualify again. A refinance means new underwriting. A job change, a drop in income or a lower appraisal can close that door exactly when you want it open.
5. Forecasts do not promise a drop. As noted above, Fannie Mae and the MBA both see rates near 6.7% to 6.8% through 2027.

None of that changes my view. It just means the right way to use the idea is to treat a future refinance as upside, not as part of the budget.

How to use a rate spike if you are buying this fall

If you are financially ready and planning to stay in the home at least five to seven years, this is how I would approach the next few months.

1. Get fully underwritten now. In a slower market, a clean, strong offer from a buyer who is ready to go carries real weight. Pre-approval at today’s rate also tells you your real ceiling.
2. Look at what has been sitting. Homes past their second weekend, and homes with a price cut, are where sellers are most flexible. Ask for the original list date and the price history.
3. Negotiate more than price. Seller credits toward closing costs, or toward a rate buydown, can be worth more to you than the same dollars off the price. Ask your lender to price both.
4. Keep your contingencies. The inspection and mortgage contingencies that buyers were waiving in 2021 and 2022 are back on the table. Use them.
5. Compare lenders on the full Loan Estimate. Points, credits and the APR matter. Ask each lender what their refinance fees would be later, too.
6. Move while the window is open. In 2022 the discount was largest in the three or four months after rates spiked. By the following spring it was mostly gone.

If you want to run your own numbers, our mortgage calculators let you try different prices and rates. If you own a home and are deciding whether to sell into this market, start with a home value estimate. For more on how the condo market is holding up at these rates, see our recent piece on Massachusetts condo prices versus single family, and more buyer guides are under buying properties.

My take

Most buyers wait for rates to come down. When they do, those buyers come back all at once, and the house you could have bought for 97.8% of list sells for 102% with no contingencies. You can change your rate later. You cannot change what you paid.

That does not make a 7% rate a good thing on its own, and it does not mean everyone should buy right now. It means that if you were already ready, a spike like this one is often a better time to be a buyer than it looks. If you want to talk through what that looks like in the towns you are considering, reach out or call or text me at 617-955-2224.
