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

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

The snapshot

  • Closings tracked, last 6 months: 224
  • Median sold price, last 6 months: $399,995
  • Median sold $/sqft, last 6 months: $237
  • Middle half of sales closed between: $312,000 and $490,000

What the numbers say

Resideline tracked 224 closed sales in Mundelein over the last six months, with a median closing price of $399,995. 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 $312,000 and $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 222 closings with usable living area, the middle half sold between $210 and $256 per square foot.

Medians hide the shape of a market. The distribution above covers the closed sales Resideline tracked in Mundelein 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 $312,000 and $490,000. Among the 91 Illinois markets with a published band, Mundelein's middle-half spread ($312,000 to $490,000) ranks 20th from the narrowest. Where your target property sits inside that spread matters more than the citywide median.

How long a sale takes here

  • Listed to under contract: a median of 31 days, across 100 Mundelein closings Resideline tracked in the last six months
  • Contract to closing: a median of 21 days, across 58 Mundelein 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 224 closings above: a sale is counted here only when we hold both of its dates.

The Mundelein angle

Mundelein's last six months of tracked closings, 224 in all, produced a median closed sale price of $399,995 and a middle half running from $312,000 to $490,000. That spread is close to typical for the markets we track, which is the quiet, useful case: the median is neither so tight that it prices homes on its own nor so wide that it means nothing. Read it as the market's center of gravity and the band as the zone where an ordinary closing lands. A valuation built from matched closed sales should usually finish inside that zone, and when it does not, the gap is a prompt to re-examine either the comps or the assumption that the subject is an ordinary Mundelein property.

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 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 Mundelein 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 Mundelein over the last six months, and is refreshed when the data is. The closings we track within the Mundelein 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 17% of the 224 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $405,990.
