It Didn't Break. It Evolved: What Six Months of NJ Market Data Actually Show

What happened in the New Jersey housing market in the first half of 2026? Across Hunterdon, Mercer, Monmouth, Morris, Somerset, and Warren counties, inventory swelled through the spring, peaked in mid-May, and has since contracted sharply while closings stayed strong — a pattern that rewarded well-prepared, well-priced listings rather than a market that simply favored buyers or sellers.

Six Months, Nine Thousand Closings

I've been tracking these six counties every week since the first Monday in January. By the first week of July, that adds up to more than 9,400 closed transactions across Hunterdon, Mercer, Monmouth, Morris, Somerset, and Warren combined.

That's not a market that stalled out. That's a market that kept moving, even while the conversation around it kept shifting.

Here's what the data actually shows, week over week, county by county.

The Inventory Arc: Shortage, Surplus, Then Tightening Again

January started with a real supply problem. In the first week of the year, Hunterdon had just 5 active listings against 22 recent closings. Monmouth had 95 actives against 112 sold. There simply weren't enough homes to go around.

Then inventory built. Steadily, week after week, active listings climbed across every county through the spring. The peak came in mid-May: Monmouth topped out at 292 active listings on May 18, Morris hit 212, Somerset reached 140. For a few months, buyers had more to choose from than they'd had all year.

Since that mid-May peak, inventory has pulled back in every one of these six counties, and pulled back hard. Monmouth is down to 164 actives as of the most recent week, a drop of roughly 44% from its high point. Morris fell even further, from 212 down to 79, a 63% contraction.

That's the part most market commentary misses. It's not that inventory "dropped." It's that a five-month buildup unwound in about seven weeks, right as closings held steady or climbed.

What "More Sold Than Active" Actually Means

Here's the number that stands out most: in the most recent week on record, Morris County closed 151 homes while carrying just 79 active listings. That's a sold-to-active ratio of 1.91 — nearly two closings for every home currently on the market.

Every one of the six counties is now running a sold-to-active ratio above 1.0. Hunterdon, Somerset, and Warren are all above 1.5. Compare that to mid-April, when every county's ratio sat between 0.25 and 0.44 — meaning four or five active listings for every one that closed that week.

That swing, from a market flooded with choices to a market clearing faster than it's restocking, happened over about twelve weeks. It's a much bigger and faster shift than "inventory is tight again" suggests.

Price Adjustments Climbed All Spring. Now They're Easing.

This is the one place where the popular read on this data gets it backwards. Price changes didn't fall over the first half of the year. They rose, and rose consistently, as more inventory hit the market and sellers adjusted to real competition for the first time in months.

Monmouth's weekly price-change count climbed from the 30s and 40s in January to a peak of 145 on June 15, the highest single week of the entire period. Mercer and Morris followed similar upward paths through the spring.

What's genuinely new is the last two to three weeks. Monmouth's price changes dropped from that June 15 peak of 145 down to 62 by the first week of July. That's a real signal, but it's a recent one, not a six-month trend. Sellers who are listing now, after watching a full spring of price discovery play out, are starting closer to where buyers actually value the home. That's the maturity showing up, and it's brand new.

County by County: The Six-Month Totals

• Monmouth — 3,263 total sales, the highest volume by a wide margin, and still setting the pace for the region.
• Morris — 2,181 total sales, and currently the tightest, most efficient market of the six.
• Mercer — 1,490 total sales, consistent and steady nearly every week of the year.
• Somerset — 1,327 total sales, without a single dramatic swing — just a quietly healthy market from January through July.
• Hunterdon — 638 total sales in a smaller, hyperlocal market that never lost momentum despite thin inventory most of the year.
• Warren — 570 total sales, the smallest of the six counties and still remarkably resilient.

The Real Takeaway

The first half of 2026 wasn't a buyer's market or a seller's market. It was a market that rewarded preparation.

Homes that were priced accurately from day one, presented well, and marketed with intention sold quickly, in some counties faster than new inventory could replace them. Homes that weren't sat, got price-adjusted, or came back on the market for a second try.

That's not a story about timing. It's a story about readiness, and it's exactly why the second half of the year deserves a real conversation about your specific home and your specific county, not a generic headline about "the market."

FAQ: First Half of 2026 NJ Housing Market

Is the NJ housing market slowing down in 2026? No. Closings across Hunterdon, Mercer, Monmouth, Morris, Somerset, and Warren counties totaled more than 9,400 homes sold between January and early July 2026, and the most recent weeks show sold-to-active ratios above 1.0 in every county, meaning homes are closing faster than new inventory is replacing them.

Why did inventory rise so much in the spring of 2026? Active listings across all six counties climbed steadily from January through a peak around May 18, 2026, as more sellers entered the market. Since that peak, inventory has contracted sharply, down more than 40% in Monmouth and more than 60% in Morris.

Are home sellers dropping their prices in New Jersey right now? Price adjustments actually increased steadily from January through a mid-June peak as competition grew. Only in the final two to three weeks of the data has that trend started to ease, suggesting sellers are now pricing closer to market value from the start rather than adjusting repeatedly after listing.

Which NJ county had the strongest housing market in the first half of 2026? Monmouth County led in total volume with 3,263 closings, while Morris County currently shows the tightest supply relative to demand, closing nearly two homes for every one active listing as of early July 2026.
