A buyer cross-shopping Summit against Chatham or Westfield this spring pulled up Redfin's tracking and found a number that stopped the search cold: Summit's median sale price in March 2026 was down 13.7% year over year, to $1.2 million. On a portal, that reads like a market losing steam. It reads like an opening to negotiate.
It isn't. In that same March 2026 snapshot, Summit's price per square foot rose to $661, homes were selling in 13 days instead of 15, and the Redfin Compete Score put the town at 97 out of 100, among the most competitive markets it tracks. The median fell. Nearly everything else that measures actual demand went the other direction. That contradiction is the whole story, and it matters more to a comparison shopper than the headline number does.
The Trouble With Averaging Eight Houses
Here is the mechanical reason the median misled. Only 8 homes closed in Summit in March 2026, down from 15 the year before. In a town that thin, the median stops describing the market and starts describing which specific houses happened to close that month. Two updated colonials near the train sell in the same month as a run of smaller condos and townhouses, and the median drops. Two estate sales close together, and it jumps. Neither move tells you whether values actually changed.
| Metric, March 2026 vs. March 2025 | Reading |
|---|---|
| Median sale price | $1.2M, down 13.7% |
| Price per square foot | $661, up 2.8% |
| Days on market | 13 days, down from 15 |
| Homes sold that month | 8, down from 15 |
Read left to right and the story flips. A median built on eight transactions has almost no statistical weight. Price per square foot, by contrast, normalizes for the mix of what sold, and it moved up.
The Numbers That Didn't Move With the Median
The most current read available bears this out. MLS data compiled through August 9, 2026 showed Summit's average sale price sitting around $1.65 million for the prior 30 days, with days on market down 11.6% and the average sale price relative to asking price up 5.3% over the same window. A market where homes are closing faster and selling closer to, or above, list price is not a market in retreat.
Zillow's Home Value Index, which is built specifically to smooth out the kind of small-sample noise that a thin month of closings produces, told the same story: Summit's typical home value sat just above $1.1 million in the same stretch, higher than it had been a year earlier. Two volume-insensitive measures pointed up. One volume-sensitive measure pointed down. When that split happens, the volume-sensitive number is the one lying.
None of this is unique to Summit in isolation. Northern New Jersey's Midtown Direct towns have been drawing renewed buyer interest through 2026 as return-to-office mandates tighten and proximity to Manhattan regains value, with towns like Maplewood, Montclair, Summit, and Morristown named among the beneficiaries. Summit's version of that demand shows up in a specific way: a market that trades fast and holds price even when the headline metric wobbles.
Why the Market Stays This Thin
A market that closes single digits of homes in a given month isn't thin by accident. Summit has spent more than a decade making it structurally difficult to add housing, and that scarcity is exactly what keeps the median so volatile and the competition for what does list so sharp.
The clearest evidence of that difficulty is Broad Street West, the redevelopment site that has defined Summit's downtown planning fights since 2014. What began as a roughly 140-unit rental proposal became, in the words of one local outlet, a project that "launched 1,000 yard signs." The Common Council delayed a scheduled July 2022 vote to September, then rescinded its own approved amendments days later after resident pushback. By October 2023, the council had voted to repeal the redevelopment ordinance outright, resetting a process that had already run for nearly a decade.
The friction hasn't resolved in 2026. In May, the city's plan to sell its former firehouse property at 396 Broad Street for $5 million to developer K&K, also known as Garden Homes, collapsed when the developer withdrew without a public explanation. The council tabled a proposal to immediately rebid the site, with one member arguing the city needed updated appraisals before setting a new minimum price. A property tied to Summit's redevelopment ambitions for years is, as of this writing, back to square one.
What's Actually Coming to Market
The housing that is moving forward in Summit right now is arriving through a different channel entirely: state-mandated affordable housing obligations rather than market-rate development. New Jersey's Fourth Round housing rules assigned Summit a present need of 59 rehabilitation units and a prospective need of 345 new construction units. On February 12, 2026, a Superior Court judge approved Summit's amended Housing Element and Fair Share Plan and dismissed a remaining legal challenge, directing the city to adopt its implementing ordinances by March 15, 2026.
The mechanics of that plan show how modest the near-term supply increase actually is. One overlay zone covering the Central Retail Business District was amended to allow 20 units per acre with a 20% affordable set-aside, but capped at three stories because the zone overlaps the city's Historic District. A separate overlay near Morris, Plain, and Aubrey held density to 12 units per acre. Another allows an existing office building at 25 DeForest Avenue to convert to residential use, also capped at three stories. This is the shape new housing takes in Summit: small, height-restricted, spread across scattered parcels, not a single project that meaningfully loosens inventory for the single-family and luxury segment most buyers are actually comparing town to town.
Smaller infill continues elsewhere on its own timeline. A zoning application filed in July 2026 proposes replacing an existing roughly 7,748-square-foot building at 11-15 Beechwood Road with a mixed-use structure of about 12,002 square feet, combining ground-floor retail with office and residential space above. It is still working through review by the Zoning Board of Adjustment, one more example of Summit adding capacity a parcel at a time rather than through the kind of larger redevelopment that keeps stalling.
Reading Summit Correctly When You're Comparing Towns
If you're weighing Summit against Westfield, Chatham, or Madison using portal medians alone, you're comparing noise. The more reliable comparison points are the ones that don't swing with a handful of closings: price per square foot, days on market, and sale-to-list ratio, tracked over a few months rather than one. On every one of those measures, Summit has held or gained ground through 2026 even while its median bounced.
The supply story explains why that holding pattern is likely to continue. A decade of stalled redevelopment, a firehouse sale that fell through in May, and an affordable-housing plan capped at three stories in most overlay zones all point to the same conclusion: Summit's inventory constraint isn't a temporary market condition. It's closer to a structural feature of the town, and it's a meaningful part of why homes here keep trading quickly even in months when the median says otherwise.
Questions Buyers and Sellers Ask Us About This
Is Summit's housing market actually cooling in 2026? The data that isolates value from transaction mix, price per square foot, days on market, and the Zillow Home Value Index, all moved up or held steady through 2026. The median's decline in March reflected which eight homes closed that month, not a shift in what buyers were willing to pay.
Will the affordable housing overlays change Summit's inventory picture soon? Not meaningfully for buyers targeting single-family homes. The approved overlay zones are capped at two to three stories in most cases and are concentrated on specific parcels, not a townwide increase in market-rate supply.
What should a seller take from a market this thin? A low-volume market punishes mispricing more than it rewards patience. With days on market falling and sale-to-list ratios rising through mid-2026, well-prepared listings are still moving quickly. Homes that sit tend to do so because of price or presentation, not because demand has softened.
