Union, NJ Housing Market 2026: What Homes Actually Sell For

If you invest in or around Union, the number that matters is what homes actually close for, not what sellers are asking. Here is what Union sale prices look like right now, built from the closings Resideline tracked over the last six months, as of October 2026.

The snapshot

• •Closings tracked, last 6 months: 231
• •Median sold price, last 6 months: $595,000
• •Median sold $/sqft, last 6 months: $383
• •Middle half of sales closed between: $500,000 and $680,317

What the numbers say

Resideline tracked 231 closed sales in Union over the last six months, with a median closing price of $595,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $500,000 and $680,317. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. 91% of the Union closings we track here are single-family houses, so these figures primarily reflect that segment, and the citywide $/sqft figure primarily reflects that segment as well.

The Union angle

Union, New Jersey turned in 231 tracked closings over the last six months, with a median closed sale price of $595,000 and the middle half landing between $500,000 and $680,317. That spread is among the tightest we track, so the tracked market here behaves consistently: most closings sit within a compact distance of the median, and the citywide figure genuinely describes a typical sale. The work in Union is less a question of finding the market level and more one of placing the specific property, because a tight band leaves little cover for a mispriced estimate. Match comps on the attributes that matter, and expect the closed data to referee any disagreement quickly.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator, rehab cost estimator, BRRRR calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Union address through Resideline and you will see the local market and the property's value together, in one report.

The local market statistics in this report are calculated from closed sales tracked by Resideline. Transaction coverage may differ from complete county or municipal records.

Every local market figure on this page is computed from closed sales Resideline tracked in Union over the last six months, and is refreshed when the data is. The closings we track across Union Township are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 18% of the 231 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone matched it at $595,000.
