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

If you invest in or around Darien, the number that matters is what homes actually close for, not what sellers are asking. Here is what Darien 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: 163
• •Median sold price, last 6 months: $450,000
• •Median sold $/sqft, last 6 months: $247
• •Middle half of sales closed between: $346,750 and $600,000

What the numbers say

Resideline tracked 163 closed sales in Darien over the last six months, with a median closing price of $450,000. 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 $346,750 and $600,000. 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 161 closings with usable living area, the middle half sold between $218 and $280 per square foot.

The Darien angle

Darien in Illinois carries a thin closed-sale record by the standards of the markets we track, which limits how much a comp screen can ask for. 163 closings is the pool before filters, so stacking property type, size, condition and a short radius often leaves too little to work with. The band from $346,750 to $600,000 is ordinary in width, which means $450,000 is a reasonable indicative reference. The distribution leans up: from $450,000 to $600,000 covers more ground than from $346,750 to $450,000. Because the pool is shallow and the high side is the more spread-out one, an estimate above the midpoint is the most fragile kind here. It should rest on the closest matches you can find, be quoted as a range, and state how many sales it draws on.

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 Darien 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 Darien over the last six months, and is refreshed when the data is. The closings we track within the Darien 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 20% of the 163 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $469,500.
