What Does It Cost to Sell a House in Illinois? A 2026 Guide for Western Suburbs Sellers
Most sellers know about the real estate commission, but it’s only one of several costs that come out of your proceeds at closing. Here’s what to expect when you sell a home in Illinois, with a focus on DuPage, Will, Kane and Kendall counties, where I do most of my work.

The main costs at a glance
| Cost | Who usually pays | What to expect |
|---|---|---|
| Real estate commission | Seller (negotiable) | Set in your listing agreement. Since August 2024, how the buyer’s agent is paid is negotiated separately, and sellers can choose whether to offer it. |
| State transfer tax | Seller | $0.50 per $500 of the sale price ($1 per $1,000). |
| County transfer tax | Seller | $0.25 per $500 of the sale price ($0.50 per $1,000). |
| Municipal transfer tax | Varies by town | Some towns charge one and some don’t. Who pays is set by local ordinance or the contract. |
| Owner’s title insurance | Seller (by custom in the Chicago area) | Based on the sale price. Your attorney orders the title commitment. |
| Real estate attorney | Seller | Almost every Illinois home sale uses attorneys on both sides. Most charge a flat fee; ask for a quote up front. |
| Property tax proration | Seller credits the buyer | Illinois taxes are paid a year behind, so you credit the buyer for taxes owed through closing. |
| Mortgage payoff | Seller | Your remaining loan balance plus interest through the payoff date. |
| HOA or condo documents | Seller | Associations often charge for the resale disclosure package and a paid assessment letter. |
| Survey | Often the seller | Many Chicago-area contracts call for the seller to provide a plat of survey. |
| Repairs or credits | Negotiated | Whatever you agree to after the buyer’s inspection. |
Transfer taxes: a quick example
On a $500,000 sale, the Illinois state transfer tax is $500 and the county transfer tax is $250, so $750 total before any municipal tax. On a $750,000 sale it’s $750 plus $375, or $1,125.
Some municipalities add their own transfer tax or require a fee, inspection or water meter reading before they’ll issue the stamps needed to close. Ask early, because a required inspection can add a step to your timeline.
Property taxes: the cost sellers forget
Illinois property taxes are paid in arrears. The bill you pay in 2026 covers 2025. So when you sell, you still owe taxes for the part of the current year you’ve owned the home. That amount is credited to the buyer at closing, and in DuPage County, where tax bills are often several thousand dollars or more, it can be one of the largest line items on your closing statement. Because the current year’s bill isn’t out yet, the credit is usually based on the most recent full bill. Your attorney and the contract set the exact formula.
Commission after the 2024 rule changes
Since August 2024, listings on the MLS no longer show an offer of compensation to the buyer’s agent. As a seller, you can still offer to pay the buyer’s agent, agree to a credit in the contract, or leave it to the buyer. I’ll walk you through how each option affects the buyers you attract and your bottom line.
How to keep more of your sale price
- Price it right the first time. Homes that sit and take price cuts usually net less than homes priced correctly from day one.
- Fix the small stuff before you list. A $300 repair now is often cheaper than a $2,000 credit after the inspection.
- Gather documents early. Survey, HOA package, permits and warranties. Delays can cost you a buyer.
- Know your net, not just your price. Compare offers on what you actually walk away with, including credits, closing date and financing risk.

Frequently asked questions
Who pays transfer tax in Illinois, the buyer or the seller?
The seller customarily pays the state and county transfer taxes. Municipal transfer taxes vary by town, and some are paid by the buyer.
Do I need an attorney to sell a house in Illinois?
It isn’t strictly required by law, but almost every residential sale in the Chicago area uses a real estate attorney for both the buyer and the seller, and standard Chicago-area contracts include an attorney review period. I can recommend attorneys I work with regularly.
How much does it cost to sell a house in Illinois?
It depends mostly on the commission you agree to, your property taxes and any credits after inspection. Transfer taxes, title insurance and attorney fees add a smaller, more predictable amount. The best way to know is a net proceeds estimate for your specific home.
