Willowbrook's 12-month detached median is $575,000 through September 2026, down 13.5% from a year ago. This fall, competition is rising: 28 detached homes were for sale at the end of September, up 75%. Willowbrook also shares ZIP code 60527 with Burr Ridge, where homes sell for about $1.1 million, which makes online estimates unreliable here.

Willowbrook is a small market inside the 60527 ZIP code, and that distinction matters. Only Willowbrook sales tell you what a Willowbrook home is worth.
Mike Berg's analysis of the September 2026 numbers: The 12-month detached median fell from $661,875 in May to $630,000 in June, $580,000 in July, $576,000 in August, and $575,000 in September. The drop has nearly stopped, but the fall market is soft. Detached inventory jumped 75% to 28 homes, September new listings doubled from a year earlier, and only 1 detached home went under contract in September, compared with 6 a year ago. Closed sales are still up 8.5% for the year and homes sell in 53 days on average. Right now, Willowbrook rewards sellers who price right on day one and punishes those who test the market.
After 14 years as a licensed appraiser and selling homes across the western suburbs since 2004, including many 60527 sales, Mike Berg sees these factors drive value in Willowbrook:

Pricing a Willowbrook home takes an appraiser's method and an understanding of the 60527 ZIP code.
"In Willowbrook, the 60527 ZIP code is both an asset and a trap. Buyers love the address. But sellers who let an algorithm price their home from 60527 data start with the wrong number. I live here and have worked this market since 2004. I know which sales are real comps and which ones are noise."

Some unincorporated pockets with grid-style addresses, such as 10W533 or 24S400, may be on a private well, a septic system, or both rather than public water and sewer. That affects buyer financing, inspections, and value, so confirm the water and sewer source before pricing.
