Updated October 2026. This Naperville page covers what trips up sellers without a realtor at closing: a city split between DuPage and Will counties, Illinois property taxes paid a year late, the tax credit you give the buyer, and the transfer stamps. Values are Zillow’s September 2026 index.
As of October 2026, the typical Naperville home is worth $618,500, up 4.5% in a year (Zillow). If you sell without a realtor, plan for one big closing item many owners miss: Illinois property taxes are billed a year behind, so you’ll credit the buyer for this year’s taxes at closing. Next door, we run the same numbers to sell your home without a realtor in Aurora, IL. DuPage County’s 2025 bills were due June 1 and September 1, 2026.

A typical Naperville home is worth more than twice the state figure. Before you pick a price, get a home value estimate specific to your property and neighborhood, then check recent sales in your subdivision. Families shopping here often compare suburbs closely; our list of Top 5 Best Suburbs In The U.S. To Raise A Family In 2023 shows what those buyers look for.
Is your Naperville home in DuPage or Will County?
Naperville is a city in both DuPage and Will counties, and its neighbor Aurora adds Kane and Kendall (see flat fee MLS in Aurora, IL). Your county decides who sends your tax bill, where the deed is recorded and which treasurer you check for unpaid taxes before closing.
Start with your tax bill or your Property Index Number (PIN). Our guide to the Illinois property tax number shows where to find it. Then look up your parcel on the right county site:
- DuPage County: the Treasurer’s site shows the bill, the two installments and payment status.
- Will County: the Treasurer’s site lists “2025 Taxes Payable in 2026” and lets you find a PIN by address.
The deadlines differ by county, so don’t copy a neighbor’s dates. For example, the Will County Treasurer’s portal says payments must post by November 30, 2026 to avoid the tax sale on December 1. DuPage set its 2026 due dates at June 1 and September 1.
School district matters to buyers too. Naperville homes feed into Naperville Community Unit School District 203 or Indian Prairie School District 204, depending on the address. Put the district in your listing so buyers don’t have to guess.
How do property taxes work when you sell a Naperville home?
This is the part that surprises sellers. The DuPage County Treasurer puts it plainly: in Illinois, property taxes are billed and collected in arrears, so your 2025 taxes are billed and collected in 2026. When you sell, you’ve lived in the home for part of 2026, but the 2026 bill won’t arrive until 2027. The buyer will pay it.
So at closing you give the buyer a credit for your share of this year’s taxes. The contract says how it’s figured. Often it’s based on the most recent full bill, sometimes with a small cushion. Your attorney and the title company put the number on the closing statement.
Here’s a simple example with a round number. Say your last full tax bill was $10,000 and you close on December 1, 2026. You owned the home for 334 days of 2026. Your credit to the buyer is about $10,000 × 334 ÷ 365, or $9,151. If any 2025 installment is still unpaid at closing, it’s paid from your proceeds too.
Which exemptions should you check before you list?
Make sure your current bill shows every exemption you qualify for, because they lower the bill your credit is based on. The General Homestead Exemption applies to owner-occupied homes. In counties next to Cook County, which includes DuPage and Will, it can reduce the equalized assessed value by up to $8,000 (Illinois Department of Revenue). Senior and disability exemptions are separate.
What transfer taxes do you pay when selling in Naperville?
There are state, county and city stamps. Illinois taxes a transfer at 50 cents for each $500 of value (35 ILCS 200/31-10). On $618,500, that’s about $619. The county recorder sells these stamps when the deed is recorded (35 ILCS 200/31-15).
Naperville has its own stamp at $1.50 per $500 of price, rounded up to the next $500. Under city ordinance, buyers of property in incorporated Naperville buy it. On $618,500, that’s about $1,856. The city asks for a Statement of Open Account at least seven business days before closing, so request yours early (City of Naperville).
Two more Illinois rules to keep in mind. You must give the buyer the Residential Real Property Disclosure Report before the contract is signed (765 ILCS 77/20). For homes built before 1978, the federal lead paint disclosure applies too (EPA). If your buyer has a loan, the lender follows federal mortgage and real estate consumer protection rules from the Consumer Financial Protection Bureau, including the Closing Disclosure the buyer gets before closing.

Buy a home →Do you need a realtor to sell in Naperville?
No, it’s not required; it’s your choice. An agent prices the home, markets it, runs showings and negotiates for you, for a fee you agree on. On your own, you do that work and keep more of the price. Many Naperville sellers land in the middle: they list on the MLS themselves and hire an attorney for the contract. Sellers up in Cook County can compare Schaumburg flat fee MLS plans, which go on the same MRED.
Most Chicago-area buyers search homes that come from MRED, the regional MLS, and our Chicago flat fee MLS rankings compare the plans that list there.

Yes. Illinois doesn’t require an agent; it’s your choice. You still follow the state disclosure law, the transfer stamp rules and your contract.
Do I still need to pay a buyer’s agent commission?
No, it isn’t required. You choose whether to offer buyer-agent compensation, and how much; it’s negotiable and not set by law or NAR rules. Since August 17, 2024, such offers can’t be shown on the MLS (NAR).

What disclosures are required when selling a home in Illinois?
The Residential Real Property Disclosure Report, delivered before the contract is signed (765 ILCS 77/20), and the federal lead paint disclosure for homes built before 1978 (EPA).
How do I handle showings without a realtor?
Set showing windows, ask for pre-approval before private tours and lock away valuables. ShowingTime, where the MLS offers it, lets buyer agents book while you approve from your phone.
Can I negotiate the contract myself when selling FSBO in Naperville?
Yes. You can negotiate price, dates and credits yourself. Have your attorney read the final terms before you sign, including the tax proration line.
How long does it typically take to sell a home without a realtor?
Plan on about two months. Nationally, the median home sold in 33 days in September 2026 (NAR), and closing often takes 30 to 45 days after that.
What happens if a buyer’s agent submits an offer on my FSBO home?
Treat it like any offer. If the agent asks for compensation, you decide whether to pay it and agree the amount in writing with that agent. It’s your choice, and it’s negotiable.
Do I need a real estate attorney to close in Illinois?
It’s your call, and we recommend one. The attorney reviews the contract, orders payoffs and handles the tax proration and stamps with the title company.
Is the Naperville housing market favorable for FSBO sellers?
Values rose 4.5% in the year to September 2026, to $618,500 (Zillow). Rising prices help, but buyers still compare, so price close to recent sales and get on the MLS.
Prices as of November 2026; Concierge is $1,399 and Basic is $129 in California and Illinois ($99 elsewhere). “$0 at closing” means no Beycome fee at closing; other closing costs, taxes, stamps, title and any agreed buyer-agent compensation still apply.
Beycome Title: Florida, Texas, Michigan, Ohio, Illinois and Indiana. The tax credit example uses a round, made-up bill; your contract and title company set the real figure. General information, not legal or tax advice; rules vary by state, county and MLS.
