Wilmette, IL Housing Market 2026: What Homes Actually Sell For

If you invest in or around Wilmette, the number that matters is what homes actually close for, not what sellers are asking. Here is what Wilmette 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: 201
• •Median sold price, last 6 months: $1,165,000
• •Median sold $/sqft, last 6 months: $451
• •Middle half of sales closed between: $720,000 and $1,753,000

What the numbers say

Resideline tracked 201 closed sales in Wilmette over the last six months, with a median closing price of $1,165,000. 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 $720,000 and $1,753,000. 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 185 closings with usable living area, the middle half sold between $363 and $530 per square foot.

Where Wilmette sale prices land

Medians hide the shape of a market. The distribution above covers the closed sales Resideline tracked in Wilmette over the last six months that carry a usable sale date, trimmed to the 5th through 95th percentile, with the middle half of sales closing between $720,000 and $1,753,000. Among the 91 Illinois markets with a published band, Wilmette's middle-half spread ($720,000 to $1,753,000) ranks 83rd from the narrowest. Where your target property sits inside that spread matters more than the citywide median. Measured as the ratio of the upper to the lower quartile, its middle-half spread ranks in the 91st percentile of the 2,291 US markets in Resideline's national Market Watch set, on data as of November 3, 2026.

How long a sale takes here

• •Listed to under contract: a median of 29 days, across 104 Wilmette closings Resideline tracked in the last six months
• •Contract to closing: a median of 10 days, across 78 Wilmette closings Resideline tracked in the last six months

Both are measured from the closings themselves, not from listing inventory. Each sale is timed using its own listing and contract dates. That is why these counts are smaller than the 201 closings above: a sale is counted here only when we hold both of its dates.

The Wilmette angle

Wilmette gave us 201 tracked closings over the last six months, and the striking figure is not the median of $1,165,000 but the territory surrounding it: the middle half of sales ran from $720,000 to $1,753,000, a spread among the widest we track. The upper stretch of that band also runs further from the median than the lower stretch does, so drifting toward the top of the Wilmette market moves an estimate in larger dollar increments than the equivalent drift downward. Both facts push the same direction. A citywide figure describes this market poorly, upper-end pricing errors are the expensive kind, and closed sales matched carefully to the subject are the only instrument precise enough for the job.

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 Wilmette 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 Wilmette over the last six months, and is refreshed when the data is. The closings we track within the Wilmette city limits 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 21% of the 201 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $1,220,000.
