Jersey County tax codes and the annual tax sale
Jersey County bills real estate taxes a year behind. The tax year 2025 bills were due in two installments, on July 24 and September 4, 2026. Rates across the county's 45 tax codes run from about 5.52 to 7.64 per $100 of equalized assessed value, with the top rate in Jerseyville. For a typical home, that top rate works out to roughly 2.55 percent of market value a year before exemptions. The general homestead exemption can take up to $6,000 off an owner-occupant's equalized assessed value. Because taxes are paid a year behind, sellers usually give the buyer a prorated tax credit at closing.
Unpaid taxes go to the Treasurer's annual tax sale in the Jersey County Government Building auditorium, and a 2026 date hadn't been posted as of mid-August. Only the delinquent taxes are sold, not the house. You redeem them through the County Clerk's office. On a home, the redemption period generally runs up to 3 years from the sale, and the tax buyer can ask the court for a deed near the end of it.
Foreclosure at the Jerseyville courthouse and local help
Every Illinois mortgage foreclosure has to go through court, and Jersey County cases are filed with the Circuit Clerk at the county courthouse in Jerseyville. Early in the case, Illinois law lets you reinstate the loan by paying the missed amounts and costs, so ask the lender for the figure. Your right to redeem by paying off the loan runs until the later of 7 months from service or 3 months from the judgment, and it ends before the sale. After the sale, the court holds a hearing to confirm it before the buyer can take possession. The Illinois foreclosure timeline and the deadline calculator lay out each step.
No county-specific foreclosure mediation program turned up, but there is help nearby. Land of Lincoln Legal Aid's Western Regional Office in Alton gives free civil legal help to Jersey County residents at (618) 462-0029 or (800) 642-5570. The Illinois Valley Economic Development Corporation, which serves Jersey, Macoupin, Greene and Calhoun counties, runs a Homeless Prevention program that can pay up to 3 months toward your mortgage if a crisis beyond your control put you behind and that crisis is now resolved. Its Jersey County line is 618-498-9521, and income guidelines apply.
Jerseyville, Grafton, Elsah and the inland villages
About 80.5 percent of Jersey County's occupied homes are owner-occupied, and the Census puts the median owner-occupied value at $171,900. Jerseyville, the county seat, is by far the largest town, with Grafton and Elsah on the river. Brighton sits mostly in Macoupin County, so check which county's name is on your tax bill.
Values split sharply by place. Grafton, the river town on the Great River Road, has a median value of $275,800, and Elsah, the historic village, sits at $221,400. Jerseyville comes in at $143,900. The small inland villages run lower: Fieldon at $91,300, Fidelity at $90,800 and Otterville at $66,000, though those tiny samples carry wide margins. That spread means a fair price depends on the town, so compare recent sales close to home.
What a $202,500 Jersey County sale leaves you
Illinois REALTORS put the Jersey County median sale price at $202,500 in the second quarter of 2026, up 13.8 percent from a year earlier, on 64 closed sales. On a traditional listing at that price, rough costs look like this:
- Agent commission at about 4.9 percent (Clever's Illinois average, updated September 2026): roughly $9,900
- Closing costs at about 1.2 percent: roughly $2,400
- State transfer tax at $0.50 per $500: about $200
That's roughly $12,600 before your mortgage payoff, repairs, the prorated tax credit or holding costs. Ask your closing attorney whether any county transfer tax or recording fees apply on top. If the property is a fit, a cash buyer may make an offer and you pick the closing date. Listing with an agent is also a fine choice. If a deadline is pushing you, the pages on selling to stop a foreclosure and selling an inherited house lay out the options.
