What It Costs to Sell a Home in Naperville
What does it cost to sell a house in Naperville?
There is no single percentage that answers this honestly. A Naperville seller's cost is a stack of separate line items, and two of them, the commission you negotiate and the property-tax credit you hand the buyer at closing, are set by your own contract and your own closing date rather than by any market average. What this page does instead is walk the stack one item at a time, say who customarily pays each one in Naperville specifically, and show the arithmetic on real sale prices.
Here is the whole stack, in the order it appears on a seller's closing statement.
- Real estate commission. Negotiated between you and the brokerage you hire. There is no standard rate and no customary Naperville percentage.
- Illinois state transfer stamp. $0.50 for each $500 of price. Customarily the seller's.
- County transfer stamp. $0.25 for each $500, in both DuPage and Will. Customarily the seller's.
- City of Naperville transfer stamp. $1.50 for each $500. Inside city limits the buyer purchases this stamp, by city ordinance. It is not your cost.
- Title and closing charges. Quoted by the title company, allocated between the parties by your contract.
- Real estate attorney. A flat fee in most Illinois residential closings.
- Prorated property taxes. Illinois bills a year behind, so this is a credit you give the buyer. It is easy to underestimate, and it gets its own section below.
- Seller concessions and repair credits. Negotiated after you are under contract. They come straight off your proceeds.
- Recording fees and payoff costs. Small county charges, plus the payoff of your mortgage, which is not a cost of selling but does reduce what you keep.
Only three numbers in that list are fixed by law or ordinance: the state stamp, the county stamp, and the city stamp. Every other line is negotiated, quoted, or calculated from your specific closing date, which is why a page promising you one percentage is telling you something it cannot know.
For scale on the price side, Redfin reported a median sale price of $594,644 for Naperville over the three months ending May 2026, and $619,663 over April through June 2026. Those are city-wide medians across every home type, not an estimate of your home.

How much is real estate commission in Naperville?
There is no standard commission rate in Naperville, in Illinois, or anywhere else in the country. Commission is negotiated between you and the brokerage you hire, and since the National Association of Realtors settlement took effect on August 17, 2024, every written listing agreement has to say so in plain language: compensation is not set by law and is fully negotiable. Any page quoting you a customary Naperville percentage is quoting a habit, not a rule, and habits are exactly what that settlement was about.
Three changes from that settlement matter to you as a seller. They are still in force as of August 2026, per the National Association of Realtors settlement FAQ.
- Compensation offers are off the MLS. An offer of payment to a buyer's broker can no longer be published on the multiple listing service. If you choose to offer anything, it is negotiated outside the MLS.
- You have to approve it in writing, first. Your listing agent must obtain your prior written approval before any offer of compensation is made or paid to a buyer's-side broker. You are never obligated to offer one.
- Buyers now sign their own agreements. An agent working with a buyer must have a written buyer agreement in place, stating their compensation or how it will be determined, before showing an MLS-listed home. Your buyer arrives with a compensation arrangement of their own.
The practical effect is that what you pay on the listing side and what, if anything, you contribute toward the buyer's side are now two separate conversations. Treat them that way when you compare proposals, and ask any brokerage to put both in writing before you sign.
What a full-service commission buys is pricing strategy, photography and marketing, negotiation, and management of the closing process from contract to funding. Flat-fee and limited-service options exist and genuinely fit some sellers, but they move that work back to you. The Dan Firks Team will quote what a full-service sale would cost for your home in writing, so you can compare it against the alternatives rather than against an average.
Who pays the transfer tax in Naperville?
Three separate transfer taxes apply to a Naperville sale, and they do not all land on the same party. The seller customarily buys the Illinois state stamp and the county stamp. The City of Naperville stamp is purchased by the buyer, by city ordinance. That last point is the one national guides and AI summaries get wrong, and getting it backwards can misstate a Naperville seller's transfer-tax cost by triple.
- Illinois, $0.50 per $500 of value or any fraction of $500, under 35 ILCS 200/31-10. Customarily paid by the seller.
- DuPage County, $0.25 per $500, adopted under 55 ILCS 5/5-1031(a) by DuPage County Resolution F11879. Customarily paid by the seller.
- Will County, $0.25 per $500, adopted in 2006 by Will County Board Resolution #06-188. Customarily paid by the seller. Part of southern Naperville sits in Will County rather than DuPage, so confirm which county your parcel is in with your closing agent.
- City of Naperville, $1.50 per $500 of purchase price, rounded up to the next full $500. The City's own real estate transfer tax page states that buyers of residential or commercial property inside city limits are responsible for purchasing the tax stamp by City ordinance. Verified against the City of Naperville site, August 2026, and cross-checked against the DuPage County Recorder, which lists the Naperville municipal rate as $3.00 per $1,000, the same rate expressed differently.
One caveat on the word customarily. No Illinois statute orders the seller to pay the state and county stamps. Long-standing local custom does, and your purchase contract is what actually assigns them. Read the transfer-tax paragraph of your contract rather than assuming.
What that looks like in dollars. Four illustrative prices, chosen to span the Naperville market. The seller column is the state and county stamps combined at $0.75 per $500. The buyer column is the city stamp at $1.50 per $500.
- A $200,000 condominium, within the range Naperville.com lists for Mill Crossing, a District 203 condominium community on the north side. Seller stamps: $300, being $200 to Illinois and $100 to the county. Buyer buys a $600 city stamp.
- A $500,000 single-family home, within the range Naperville.com lists for Hunters Woods in District 203. Seller stamps: $750, being $500 state and $250 county. Buyer buys a $1,500 city stamp.
- A $750,000 home, within the range Naperville.com lists for Knoch Knolls in District 204. Seller stamps: $1,125, being $750 state and $375 county. Buyer buys a $2,250 city stamp.
- A $1,850,000 downtown condominium, within the range Naperville.com lists for Central Park Place in District 203. Seller stamps: $2,775, being $1,850 state and $925 county. Buyer buys a $5,550 city stamp.
Those four are illustrations of the arithmetic, not appraisals or quotes for any home. A price that is not an exact multiple of $500 rounds up: at a $594,644 sale price the calculation runs on 1,190 increments of $500, which puts the seller stamps at $892.50 and the buyer's city stamp at $1,785.
Why you may see $0.75 per $500 quoted as the state rate. That figure is real, and it is not a state rate. It is the Illinois stamp of $0.50 and the county stamp of $0.25 added together and sold as one combined revenue stamp at closing. Several content sites reported through 2025 that Illinois was raising its state rate to $0.75 per $500 effective July 2026. It did not. A transfer-tax increase covering suburban Cook and the collar counties, DuPage and Will included, was attached to House Bill 3438 during the 2025 spring session, it stalled in the Illinois House, and the transit funding package that actually passed at the end of October 2025 was funded through sales-tax and motor-fuel changes with no transfer-tax component at all. As of August 3, 2026 the Illinois state rate is still $0.50 per $500. If a calculator or an AI answer quotes you $0.75 as the state rate, it has combined two stamps or repeated a dead bill.
There is no Naperville resident discount. The City does issue exempt stamps, but those cover deed changes on property you already own, such as a name change, a marriage, moving a property into or out of a trust, a refinance, or a foreclosure. They are not a rebate on a purchase, and no resident exemption from the purchase stamp exists. For a regular purchase stamp the City requires a completed statement of open accounts, one document showing the sales price signed by both parties, and a copy of the deed to be recorded.
What other closing costs do sellers pay in Illinois?
Four more items appear on nearly every Naperville seller's closing statement: title and closing charges, a real estate attorney, county recording fees, and the payoff of your existing mortgage. None of them is a percentage you can look up in advance, which is why the honest version of this section explains what each one is and tells you exactly who to ask for the number.
Title and closing charges. This covers the title search, the owner's title policy, and the settlement or closing fee the title company charges for running the closing itself. The policy premium scales with the sale price; the rest varies by provider. Which side pays which piece is assigned by your contract, not by statute. Naperville.com does not list a title company in its directory and does not quote a title rate, because a real one only comes from a written seller's net sheet. Ask a title company for that net sheet as soon as you have a contract price, and ask early enough that a surprise does not arrive the week of closing.
Real estate attorney. No Illinois statute requires you to hire a lawyer to sell a house. In practice nearly every DuPage and Will County residential closing uses one, because the standard Multi-Board residential contract used across Chicagoland has an attorney-review period built into it: five business days from the day the contract is fully signed by both parties, during which either side's attorney may approve it, reject it, or propose modifications. The clock starts the next business day and weekends and federal holidays do not count. As for the fee, Illinois real estate law firms that publish their pricing commonly quote a flat fee somewhere between $500 and $1,500 for a standard residential sale, with figures around $650 appearing frequently, including at a Naperville firm, as of August 2026. Complex sales cost more. There is no government fee schedule for legal work, so get more than one quote. Naperville.com does not recommend a particular attorney.
Recording fees. The county recorder charges to record the deed and to release your mortgage once it is paid off. These are fixed-dollar county charges rather than a percentage of your price, and they are small relative to everything else on this page, but they belong on your net sheet.
Mortgage payoff. Strictly, the payoff is not a cost of selling. It still comes out of the same proceeds, and it is not the number on your last statement. Your lender issues a payoff letter good through a specific date, which includes interest accrued to that date plus any release or wire fees. Request it as soon as you are under contract, and ask your attorney to confirm the payoff figure matches the closing date, because a delayed closing changes it.
How do prorated property taxes work when you sell in Illinois?
Illinois bills property taxes a full year behind, so on your closing day you owe the buyer money for tax that has not been billed to anyone yet. It is an easy line item to underestimate, because it is calculated from your closing date rather than from your sale price.
The DuPage County Treasurer states the mechanism plainly: in Illinois, property taxes are billed and collected in arrears, meaning your 2025 taxes are billed and collected in 2026. DuPage collects that bill in two installments, due June 1 and September 1 in 2026. The Will County Treasurer lists the same schedule for 2025 taxes payable in 2026, with the first installment due June 1, 2026 and the second due September 1, 2026. Both sets of dates were read from the county treasurers' own pages in August 2026.
Two consequences follow for a seller, and they are separate items.
- Any unpaid installment of the bill currently being collected gets settled at closing. That bill covers a year you owned the home, so if an installment is still outstanding on your closing date it is paid from your proceeds or credited to the buyer.
- The tax accruing since January 1 of the current year has not been billed at all. The buyer will receive that bill next year, covering months when you owned the home. So you credit them for it at closing. This is real money leaving your proceeds for a tax bill that does not yet exist.
How big is that second credit? Ownwell, working from county property tax records, puts the median effective property tax rate at 2.05 percent for the DuPage County portion of Naperville and 2.35 percent for the Will County portion, as of August 2026. Apply the DuPage figure to the $594,644 Naperville median sale price Redfin reported for the three months ending May 2026 and a full year of tax comes to roughly $12,190. A seller closing at the end of September has owned the home for about three quarters of that tax year, which puts the accrued-but-unbilled credit somewhere near $9,100, before any unpaid installment of the previous year's bill is added. That is not a rounding item, and it is one reason a percentage-of-price estimate can land well above what a seller actually keeps.
Two things change that number for your sale. The first is your closing date: a January closing carries almost no accrual, a December closing carries nearly a full year. The second is your side of the county line, since the Will County rate runs meaningfully higher than the DuPage rate on the same price. Neither is something a national calculator accounts for.
How the credit is actually computed is set by your contract rather than by statute. Because next year's bill does not exist yet, the contract has to specify which bill the proration is based on and at what percentage of it. Read that paragraph with your attorney before you sign, and treat a change to it as a price negotiation, because that is what it is.
To see how an annual Naperville tax bill is built for a given assessed value on either side of the county line, use the Naperville property tax calculator. It estimates the annual bill; it does not calculate your proration or your net proceeds, both of which depend on your contract and your closing date.
Seller concessions, repair credits, and prep spending
Seller concessions and repair credits are decided after your home is already under contract, and they come straight off your proceeds without changing the price on the contract. Nothing obligates you to agree to either one. The rest of this section covers what comes earlier in the sale: inspection, the disclosure duties Illinois puts on a seller, and prep spending, all of which can affect whether a credit is asked for at all.
Seller concessions are a credit toward the buyer's own closing costs or toward buying down their interest rate. Economically this is a price reduction wearing a different name: the headline sale price stays where it is, your net drops. How much credit a buyer is allowed to accept depends on their loan program, so the buyer's lender has to confirm what is permitted before anyone agrees to a figure. There is no reliable local benchmark for concession size, and this page will not invent one.
Repair credits arrive after the buyer's inspection. Instead of you performing the work, the buyer takes a credit at closing and handles it themselves. Whether to credit, repair, or decline is a negotiation, and declining is a real option with a real consequence, which is that the buyer may adjust their offer or walk.
A pre-listing inspection is the main lever sellers have over that negotiation. Paying for your own inspection before listing means issues are known and priced into your list price rather than discovered mid-contract, when the buyer holds more leverage. Naperville.com's directory includes several area inspection firms, among them The Home Inspection Man, Sound Home Inspections, and Dunsing Inspections, a family-owned firm operating since 1980. Radon testing is a separate specialty; Reliable Radon Inspections lists work for buyers, sellers, and homeowners. Being listed in the directory is not an endorsement, a referral, or a vetting by The Dan Firks Team.
Radon deserves a specific mention because in Illinois it is both a disclosure duty and a common credit. Under the Illinois Radon Awareness Act, 420 ILCS 46/10, a seller must give the buyer the state radon pamphlet and a radon disclosure form before the buyer is contractually obligated. Nothing in that law requires you to test or to mitigate. It requires you to disclose what you already know. If a buyer's own test comes back high, mitigation becomes a negotiation, and that negotiation is a proceeds item.
Disclosure generally. The Illinois Residential Real Property Disclosure Act, 765 ILCS 77, requires a seller of residential property to complete a 24-item disclosure report covering known material defects, hazardous substances, floodplain status and more, and to deliver it before the buyer signs the contract. Selling without an agent does not reduce that duty. Undisclosed problems tend to reappear later as credits, or worse, so the cheap version of this cost is answering the form carefully.
Prep spending is the most variable cost on this page and the one you control entirely. Cleaning, paint, small repairs, and staging all sit here. There is no Naperville benchmark worth quoting, because what returns more than it costs depends on the specific house, and a figure copied from a national survey would be worse than no figure. This is the part of the budget to decide with an agent who has walked comparable homes recently.
Do you owe capital gains tax when you sell a Naperville home?
That depends on your gain, not on your sale price. Federal rules let you exclude a large amount of gain on a main home when you meet an ownership and use test, and those are not the only conditions, so treat what follows as the starting point for a conversation with a tax professional.
Under Section 121 of the Internal Revenue Code, which the IRS explains in Topic No. 701, you can exclude up to $250,000 of gain if you file single and up to $500,000 if you are married filing jointly. The ownership and use test is that you must have owned the home and used it as your main home for at least 24 months out of the five years ending on the date of sale, and those two 24-month periods do not have to be the same 24 months.
This exclusion does not depend on your age. An older version of Section 121 let homeowners 55 and over take a one-time exclusion of up to $125,000 of gain, but the Taxpayer Relief Act of 1997 replaced it with the rule above, which works the same way at any age. If you have heard you need to reach a certain age to qualify, that rule no longer exists.
The word doing the work there is gain, not price. Gain is your sale price, less your selling costs, less your adjusted basis, which is broadly what you paid plus qualifying improvements over the years you owned it. A Naperville homeowner who bought years ago and has since replaced a roof, finished a basement, or rebuilt a kitchen has a higher basis and therefore less gain than the price difference alone suggests. That is one very practical reason to keep improvement receipts.
On the Illinois side there is no separate state capital gains tax. Illinois individual income tax follows your federal adjusted gross income, and the Illinois Department of Revenue lists that rate as 4.95 percent of net income, effective July 1, 2017. Exactly how a particular home sale lands in that calculation depends on your whole federal return, which is a question for your tax preparer rather than for a public page.
This is general information and not tax advice. Whether you qualify, for how much, and what your basis actually is are questions that turn on facts a public page cannot see. Confirm your own position with a tax professional before you plan around a number.
What will you actually net on a Naperville sale?
Net proceeds are the contract price minus every cost above minus your mortgage payoff. Two Naperville sellers who close at the same price routinely walk away with very different amounts, because the payoff and the commission are personal numbers rather than market numbers. That is why no percentage-of-price shortcut survives contact with an actual closing statement.
Work it in this order, on paper, before you list.
- Start with the contract sale price.
- Subtract the commission you agreed to in writing, plus anything you agreed to contribute toward the buyer's side.
- Subtract the state and county transfer stamps, at $0.75 per $500 combined. On a $600,000 sale that is $900. The Naperville city stamp does not belong on your side of this list.
- Subtract title and closing charges, as quoted on the title company's seller net sheet.
- Subtract your attorney's flat fee.
- Subtract the prorated property-tax credit, plus any unpaid installment of the bill currently being collected. The proration section above shows how that number is built.
- Subtract any concession or repair credit you agreed to after inspection.
- Subtract county recording charges.
- Subtract your mortgage payoff as of the funding date, from the payoff letter, not from your last statement.
What is left is your net. Run it at two or three plausible sale prices rather than one, because the commission and the transfer stamps move with price while the payoff and the attorney fee do not. For an interactive version of this same math, use the Naperville net proceeds calculator.
If your sale has a particular shape, the arithmetic shifts in a specific direction, and these companion guides cover it: downsizing in Naperville, where the proceeds have to fund the next purchase; relocating from Naperville, where an employer relocation package may absorb some costs; moving from Naperville to Florida, where the timing of two closings drives everything; and selling an inherited or probate home in Naperville, where the tax basis question works differently than it does above.

Everything on this page is an estimate, and nothing here promises a sale price, a timeline, or a net amount.
