Four years ago, a 6.5% mortgage rate felt temporary. Today, it looks a lot more like the market — and that shift matters for buyers and sellers from Hingham to the Seaport to Cape Cod.

We've spent years telling buyers to be patient and wait for rates to come down. But when essentially the same rate environment sticks around for four years, the conversation has to change.

A buyer who decided to wait in 2023 for significantly lower rates is looking at roughly the same rate today. What it means: the rate didn't move much — but everything else did.

What Waiting Actually Cost

Those three years still happened. A buyer sitting on the fence in Hingham, Wellesley, or Chelmsford in 2023 may have spent that time renting instead of building equity. Home prices moved higher in most of the markets we serve — the South Shore's anchor towns (Hingham, Cohasset, Scituate, Norwell, Hanover), Boston neighborhoods like Back Bay and South Boston/Seaport, Cape Cod towns from Barnstable to Chatham, Metro West communities like Wellesley and Newton, and the Merrimack Valley corridor from Chelmsford through Newburyport have all seen appreciation over that window. The home a buyer was waiting to buy may simply cost more today than it did when they first started waiting.

What it means: "waiting for rates to drop" has, for many buyers, quietly become "waiting for the same rate on a more expensive home."

The Part Nobody's Talking About: Affordability Actually Improved

Here's the interesting part. The national affordability index recently climbed to 102.3, up from 95.5 a year ago. Mortgage rates didn't dramatically improve. Affordability did.

That's because a rate is only one part of the equation. Income, wages, home prices, inventory, loan structure, and a buyer's overall financial picture all factor into what a home actually costs someone month to month. What it means: a buyer who ran the numbers a year ago and walked away may find the math works differently today — even with a nearly identical rate.

What This Means for Sellers

If you're selling in Hingham, Cohasset, Scituate, Norwell, or Hanover — or in Back Bay, Wellesley, Chelmsford, or Barnstable — this is good news, not a footnote. Improved affordability brings buyers back into the market who had priced themselves out on paper. Sellers across our markets should expect renewed buyer activity even without a major rate drop, and should price with the expectation that qualified buyers are re-entering rather than sitting out.

What This Means for Buyers

If you've been waiting for the market to become "normal" again, it's worth asking a more specific question: are you waiting for a rate that may not come back, or are you waiting for a financial picture that's already changed in your favor? Buyers eyeing the South End, Newton, Falmouth, or Andover should run their numbers against today's affordability picture — not against the rate headlines from three years ago.

Where This Leaves Us

Rates have held in a narrow band for four years. Affordability has moved anyway. The question buyers should be asking isn't "when will rates drop" — it's "does this work for me right now." If you've been sitting on the fence, send us a message. We'll run your numbers at today's market, compare them against waiting, and give you something concrete to make a decision around.

Frequently Asked Questions

Have mortgage rates actually changed much since 2023?

Not significantly. The 30-year fixed rate measured in August was 6.96% in 2023, 6.49% in 2024, 6.58% in 2025, and 6.67% in 2026 — a narrow band of roughly half a percentage point over four years. Source: Freddie Mac Primary Mortgage Market Survey, August 2023–August 2026.

If rates haven't dropped, why is affordability improving?

Affordability depends on more than the mortgage rate — income growth, wage trends, home price movement, and loan structure all factor in. The national affordability index rose to 102.3 from 95.5 over the past year even though rates stayed roughly flat.

Is it a good time to buy on the South Shore given where rates are?

For many buyers, yes — improved affordability means the math may work better now than it did a year or two ago, even with a similar rate. Hingham, Cohasset, Scituate, Norwell, and Hanover have all seen continued buyer demand, and waiting for a further rate drop hasn't historically paid off over the last four years. Buyers should run their specific numbers rather than wait on the rate headline.

How does this affect condo buyers in Boston neighborhoods like Back Bay and the South End?

Boston condo buyers face the same dynamic as suburban buyers: rates have been stable, but affordability metrics have shifted in buyers' favor. Combined with financing costs and association fees, buyers in Back Bay, the South End, and Charlestown should have their numbers re-run against current affordability data rather than assuming last year's math still applies.

Should Cape Cod buyers in Barnstable or Chatham keep waiting for lower rates?

Four years of data suggests rates in the mid-6% range may be the norm rather than a temporary condition. Cape Cod buyers waiting for a rate drop before purchasing in Barnstable, Chatham, or Falmouth should weigh that against rising seasonal home prices and the fact that affordability has already improved independent of rate movement.

What does this mean for sellers in Metro West towns like Wellesley and Newton?

Improved affordability tends to bring back buyers who had priced themselves out, which supports continued demand in competitive markets like Wellesley, Newton, and Needham even without a major rate decline. Sellers should expect qualified buyer activity to hold steady rather than assume a stalled rate environment means a stalled market.

Is this rate pattern affecting the Merrimack Valley and Chelmsford-area market too?

Yes — the four-year rate pattern is a national trend, so it applies to Chelmsford, Andover, and Newburyport buyers the same way it applies elsewhere. Given that affordability is improving independent of rate movement, buyers in this corridor who've been waiting on the sidelines may find today's numbers more workable than they expect.
