DuPage's November 19 tax sale and the township multipliers on your notice
DuPage bills come in two installments, and late payments pick up penalties. If the bill is still unpaid, the Treasurer's annual tax sale starts Thursday, November 19, 2026, in the County Administration Building auditorium in Wheaton. To keep your parcel out of it, certified funds have to reach the Treasurer's Office before 4:30 p.m. on November 18. What sells is a lien on your taxes, not the house. Bidders compete on the interest rate, which tops out at 9 percent, and the Treasurer says winning bids in recent years averaged 0 to 4 percent. Where nobody bids, the county buys the taxes itself at 9 percent, and leftover parcels aren't sold over the counter afterward. Under state law as amended in July 2026, a home with one to six units can generally be redeemed for up to three years from the sale. The Treasurer's page still quotes shorter windows of up to 2.5 years, which applied to earlier certificates, so check the date on yours.
DuPage reassesses every parcel every four years. The Supervisor of Assessments names 2019 and 2023 as general reassessment years, which puts the next one in 2027. In between, township multipliers push values up, about 6 to 7 percent for 2026 in Naperville, York, Wayne and Addison townships. If you live in the house, the homestead exemption takes up to $8,000 off your equalized assessed value here.
The 18th Circuit, a 9-month process and free counseling
Every DuPage foreclosure runs through the 18th Judicial Circuit, and the court's own foreclosure FAQ says the whole legal process typically takes about 9 months. Illinois only allows foreclosure through a lawsuit, so the clocks come from statute. Redemption runs until the later of 7 months from service or 3 months from the judgment, and the sale normally comes after that ends. Then the Sheriff sells the property at auction. A judge still has to confirm the sale, and the court's timeline says the homeowner's right to possession expires 30 days after that order.
Filings here are low. DePaul's Institute for Housing Studies counts 731 new foreclosure filings in DuPage in 2025, down from 754 in 2024, and only 81 completed auctions. That's 0.2 filings per 100 residential parcels, against 2.3 at the 2010 peak. The court's foreclosure assistance page points you to free help: H.O.M.E. DuPage, a HUD-certified housing counseling agency (630-260-2500), Prairie State Legal Services (630-690-2130), and the Illinois Foreclosure Prevention Network hotline (855-533-7411). The DuPage County foreclosure timeline and the deadline calculator lay out each date.
From $261,700 in Glendale Heights to $1,053,700 in Hinsdale
Values split hard across the county, so the same house can be worth very different money a few miles apart. The Census puts DuPage's median owner-occupied value at $391,400 for 2020 to 2024, but it's $261,700 in Glendale Heights and $272,000 in Bensenville, against $1,053,700 in Hinsdale. In between, Villa Park sits at $329,000, Addison at $341,300, Wheaton at $455,700 and Naperville at $540,200. Price the house against its own town, not the county median.
The market has loosened a little, too. Redfin counted 3,607 active listings in August 2026, up 11.4 percent in a year, with homes selling at 100 percent of list after a median 51 days.
What a $448,499 DuPage sale leaves you
Redfin put DuPage's median sale price at $448,499 in August 2026, up 4.8 percent in a year. Commission at about 4.9 percent, Clever's Illinois average (updated September 2026), is roughly $22,000. Closing costs at about 1.2 percent add roughly $5,400. The state transfer tax is $0.50 per $500 and the county's is $0.25 per $500, about $450 and $225 at that price, and by custom the seller usually pays both. Then check your town. The Recorder lists 13 municipalities with their own stamps, from $1.50 per $1,000 in Elmhurst to $7.50 in Bolingbrook. Who pays the town stamp varies by town and contract. In Glen Ellyn, at $3.00 per $1,000, it's about $1,350, so ask your title company which side covers it.
Add it up and the listing route costs roughly $31,000 before your mortgage payoff or any repairs. Carrying costs keep running while you wait, and the median listing took 51 days to sell in August. If the property is a fit, a cash buyer may make an offer, and you pick the closing date. With homes still selling at full list, listing is a perfectly good choice too. Run both numbers first.
