Wonder Lake, IL Housing Market 2026: Median Home Price, Last 12 Months

If you invest in or around Wonder Lake, the number that matters is what homes actually close for, not what sellers are asking. Here is what Wonder Lake sale prices look like right now, built from the closings Resideline tracked over the last 12 months, as of October 2026.

The snapshot

• •Closings tracked, last 12 months: 203
• •Median sold price, last 12 months: $316,990
• •Median sold $/sqft, last 12 months: $190
• •Middle half of sales closed between: $275,000 and $396,583

What the numbers say

Resideline tracked 203 closed sales in Wonder Lake over the last 12 months, with a median closing price of $316,990. 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 $275,000 and $396,583. 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 202 closings with usable living area, the middle half sold between $167 and $220 per square foot.

Where Wonder Lake sale prices land

Medians hide the shape of a market. The distribution above covers the closed sales Resideline tracked in Wonder Lake over the last 12 months that carry a usable sale date, trimmed to the 5th through 95th percentile, with the middle half of sales closing between $275,000 and $396,583. Among the 91 Illinois markets with a published band, Wonder Lake's middle-half spread ($275,000 to $396,583) ranks 4th 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 16th 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 77 days, across 118 Wonder Lake closings Resideline tracked in the last 12 months
• •Contract to closing: a median of 39 days, across 94 Wonder Lake closings Resideline tracked in the last 12 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 203 closings above: a sale is counted here only when we hold both of its dates.

The Wonder Lake angle

Wonder Lake shows 203 tracked closings over the last 12 months, a median closed sale price of $316,990, and a middle half between $275,000 and $396,583. That band is tighter than most spreads we track, so ordinary closings land within a short distance of one another and the median is genuinely informative. What tightness does not remove is asymmetry: the climb from $316,990 to $396,583 is longer than the step down to $275,000, so the stronger sales stretch further than the weaker ones do.

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