Needham's $867-a-Foot Ceiling: 674 Webster Street Sold a Million Over the Assessor's Number

Needham had bigger dollar figures in June 2026. Two homes closed north of $2.35 million on paper by sheer size — a 4,681-square-foot house on Evergreen Road at $1,900,000 and a 3,635-square-foot house on Great Plain Avenue at $1,715,000 both moved plenty of square footage. But strip out size and rank the month by price per square foot, and 674 Webster Street sits alone at the top. Its $2,350,000 sale worked out to $867 a foot — the highest per-foot number of any Needham home to close that month, and roughly 31% above the town's median of about $660. In a market where the headline price is mostly a function of how many rooms you're buying, price per foot is the honest measure of what a location commands. On that measure, this was Needham's benchmark sale of the month.

The number that closed was not the number that opened. 674 Webster Street came to market on March 17, 2026 at $2,500,000. It did not spark a same-week bidding war at that figure; instead it worked its way through the spring and closed on June 12, 2026 at $2,350,000 — about $150,000, or 6%, under the original ask, after roughly three months of marketing. That is worth pausing on, because it cuts against the reflex that anything scarce in Needham sells over ask in a weekend. It didn't. The seller opened aspirationally, the market answered with a modest correction, and the deal cleared in the low $2.3 millions. A 6% give from a spring ask is not a distressed sale — it's a normal, orderly re-rating. The lesson for sellers in Needham, Wellesley, Belmont, or Winchester is the same one the top of this market keeps repeating: the opening number is a hypothesis, and the buyer gets the last word.

Here is the figure that should make every Needham homeowner check their own assessment. The town values 674 Webster Street at $1,323,000. It just sold for $2,350,000. That is a gap of roughly $1,027,000 — the home traded at about 178% of its assessed value. The assessment isn't wrong so much as it is late: municipal rolls are built on prior-year data and lagged comparable sales, so in a fast, thin, supply-starved market the assessor is always describing the town as it was, not as it prices today. The prior sale tells the same story. The house last changed hands in December 2013 for $1,300,000 — almost exactly today's assessed value. In other words, the town roll still effectively prices this property near its 2013 number, while the open market paid 81% more. That's roughly a 4.8% compounded annual gain over about twelve and a half years, and nearly all of it is invisible on the tax card. For buyers, the takeaway is blunt: never anchor an offer to the assessed value in a prestige town — the assessment is a floor and a rear-view mirror, not a market signal.

Line the month up side by side and the pattern is clean. The largest house — 18 Evergreen Road at 4,681 square feet — sold for the lowest price per foot, about $406, because big new square footage is the most reproducible thing in the market: you can always build more of it. The smallest of the marquee sales, 22 Grant Street at 1,906 square feet, fetched a high $762 a foot precisely because you're paying for the parcel and the neighborhood, not the volume. 674 Webster Street tops the table at $867 by combining both levers — a modest interior footprint on an outsized 0.79-acre lot. When a smaller house on a bigger piece of ground out-earns a larger house per foot, that isn't a fluke. It's the market telling you what it actually values.

The through-line of every one of these numbers is land. 674 Webster Street is 2,709 finished square feet on roughly 34,500 square feet of ground — a nearly three-quarter-acre lot in a town where close-in parcels are chronically scarce and effectively un-manufacturable. At $867 a foot of building, the buyer is not paying for an unusually large or lavish house; they are paying for the location and the lot, with the structure along for the ride. That is the same lesson our appraisal and pricing tools surface again and again across Greater Boston's premium suburbs: in supply-constrained towns, the building depreciates and the land appreciates, and the price per foot on a sale like this is really a land price wearing a house's clothes. The Zestimate had this home pegged at $2,414,700; it closed at $2,350,000, about 2.7% under — close enough to confirm the automated model and the market agreed on where the value sat, even as the town's own assessment trailed a full million behind.

Concretely: a five-bedroom, three-and-a-half-bath single-family home of 2,709 square feet on a 0.79-acre lot in Needham, one of the inner-ring's most consistently demanded towns for its schools, its commuter-rail access, and its walk-to-center convenience. It is not a trophy estate and it did not need to be. What made it the per-foot leader of the month was the scarcity math beneath it — a large, close-in parcel in a town that cannot make more of them. The honest counterpoint is that a 6%-under-ask, three-month sale is not a market on fire; it's a market that is firm but disciplined, willing to pay a record per-foot number and unwilling to overpay the sticker. That is arguably the healthiest signal a prestige town can send: real value in the land, real discipline at the table.
