Union City, CA Housing Market 2026: What Homes Actually Sell For

If you invest in or around Union City, the number that matters is what homes actually close for, not what sellers are asking. Here is what Union City 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: 196
• •Median sold price, last 6 months: $1,250,000
• •Median sold $/sqft, last 6 months: $693
• •Middle half of sales closed between: $760,000 and $1,490,000

What the numbers say

Resideline tracked 196 closed sales in Union City over the last six months, with a median closing price of $1,250,000. 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 $760,000 and $1,490,000. 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. Across the 196 closings with usable living area, the middle half sold between $586 and $837 per square foot.

The Union City angle

Union City produced 196 tracked closings over the last six months, a median of $1,250,000, and a middle half running from $760,000 to $1,490,000. That spread is wider than most markets we track, and at this price level an ordinary looking percentage error turns into a very large number of dollars. The distance from $760,000 to the median is the wider of the two halves, so the weaker side of this market runs further from the midpoint than the stronger side does, and a comp set that drifts cheap will pull an estimate down hard. With a sample thinner than most markets we track, hold property type constant before you relax anything else.

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