Chicago Housing Market 2026: A $425,000 Median, Thin Inventory, the October 1 Tax Bill, and What It Means for Sellers

The Chicago housing market 2026 story is a supply story with a tax calendar attached. City prices are rising at double the statewide pace while the number of things for sale keeps shrinking, and a fall tax deadline lands on every Cook County owner at once.

Propcash keeps every source separate and labeled. Illinois REALTORS reports what closed, Zillow models a typical value across all stock, DePaul's Institute for Housing Studies publishes days on market, and Freddie Mac publishes the weekly rate.

What is the Chicago housing market doing in 2026?

Prices are rising on shrinking supply. The City of Chicago median sale price reached $425,000 in July 2026, up 13.3% from $375,000 a year earlier. Over the same twelve months the number of properties for sale in the city fell 26.3% to 3,502 (Illinois REALTORS, August 20, 2026).

Closed sales did not rise with the price. The city recorded 2,137 closings in July 2026, down 2.9%. Statewide the same pattern runs milder.

The nine-county Chicago Metro Area sat between the two, at a $401,000 median, up 6.8%, on inventory down 11.9%. Illinois REALTORS compiled the figures as of August 7, 2026.

Industry leaders point at construction. Illinois REALTORS CEO Jeff Baker put it plainly to WTTW. The shortage "would require us to triple the amount of new home construction every single year for the next five years" (WTTW, August 20, 2026). None of that is a forecast. It reports one month, and August figures are due September 24, 2026.

Why is Zillow's Chicago value lower than the $425,000 median?

The two measure different things, and combining them produces a figure that is true of nothing. Zillow's Home Value Index put the typical Chicago property at $337,993 on July 31, 2026, up 4.5%, almost $90,000 below the Illinois REALTORS median. A closed-sale median is the midpoint of what changed hands in one month. A value index covers the entire housing stock, including the bungalow on a Southwest Side block that has not traded since 1974.

Composition explains the rest. Of the 2,137 city closings in July 2026, two thirds were condominiums and townhomes at a $440,000 median. Single-family houses accounted for 713 closings at a $392,000 median (Institute for Housing Studies at DePaul University, August 2026). What sells in Chicago is not a cross-section of what stands in Chicago.

Read each table on its own terms. The figures above come from the public Zillow research files. The sale medians in the previous table come from Illinois REALTORS.

Inventory and Days on Market as Demand Signals

Both point the same way: less to buy, and what lists does not sit. City single-family inventory fell to 1,354 units in July 2026 from 1,903 a year earlier, and condominium inventory fell to 2,148 from 2,850 (IHS, August 2026).

Time on market shortened alongside it. City single-family houses averaged 25 days on market in July 2026, one day faster than July 2025, and condominiums averaged 19 days, a full week faster.

Mortgage Rates Behind Chicago Home Prices 2026

Borrowing costs moved against buyers while prices rose. The 30-year fixed-rate mortgage averaged 6.76% for the week of September 10, 2026, up from 6.71% the prior week and 6.35% a year earlier (Freddie Mac Primary Mortgage Market Survey, September 2026).

Illinois REALTORS reported the July 2026 monthly average commitment rate at 6.5%, flat from June and down from 6.7% a year earlier. IHS noted that rates have climbed since February and that affordability for Chicago buyers worsened (IHS, August 2026).

For a seller, the effect is a narrower financed buyer pool at every price. A buyer carrying a larger balance at a higher rate has less room for repair credits and appraisal gaps.

The Cook County Calendar a Chicago Seller Sells Into

Second installment bills for tax year 2025 were released September 1 and are due October 1, 2026, about 1.8 million of them (Cook County, August 2026). The first installment for the same tax year was due April 1, 2026.

How proration works at an Illinois closing

Illinois property taxes are billed and paid the year after the tax year they cover, so a seller closing this fall has usually accrued taxes that have not been billed yet. Contracts commonly handle this with a prorated credit from seller to buyer, and any bill already due and unpaid is typically settled out of proceeds. The closing attorneys and title company calculate the figures.

The 2027 reassessment sitting just ahead

Cook County reassesses each property once every three years, rotating across the county. The Assessor's calendar states that the south and west suburbs are reassessed in 2026. North suburb and City of Chicago properties are reassessed only for division work, permit applications, or other special circumstances (Cook County Assessor, September 2026). On that rotation the city's next full reassessment falls in 2027.

A reassessment notice matters to a listing because it resets the number a buyer underwrites. A financed buyer sizes escrow off the expected tax bill, so a new value arriving mid-listing changes the payment math while the house is still on the market.

The Transfer Tax a Chicago Seller Pays

A Chicago seller's customary share is $2.25 per $500 of the transfer price, stacked across three layers.

• CTA portion, $1.50 per $500: the supplemental part of the city transfer tax, carried by the transferor (Chicago Municipal Code 3-33-030).
• State of Illinois, 50 cents per $500: imposed on the privilege of transferring title, at "50¢ for each $500 of value or fraction of $500" (35 ILCS 200/31-10).
• Cook County, 25 cents per $500: "25 cents for each $500 of value or fraction thereof," collected before the deed is recorded (55 ILCS 5/5-1031).

The buyer carries the city's main $3.75 per $500 portion under the same ordinance. On a $425,000 sale the seller's share is roughly $1,913 and the buyer's roughly $3,188. Those are customary allocations, not fixed law, so confirm yours with a closing attorney.

Chicago Housing Stock, by Building Type

What you own in Chicago shapes the sale more than the citywide median does, because the city sells on building type. These are stock characteristics only, since neighborhood-level medians are too small a sample to report responsibly.

• Brick bungalows. The Bungalow Belt rings the city, with more than 80,000 still standing, roughly a third of the single-family stock (Historic Chicago Bungalow Association, September 2026). One and a half stories over a full basement, hipped roof, leaded glass, and often original electrical service.
• Two-flats and three-flats. Units in two-to-four-unit buildings are 26% of all residential units in the city and more than 35% of its rental stock (IHS, May 2021). These generate most tenant-occupied sales.
• Greystones and frame workers cottages. Limestone fronts in the pre-1920s corridors, and the city's oldest wood-frame stock on narrow lots near the river and old rail lines. Tuckpointing, parapets, balloon framing, and basements below the sewer line are routine for a cash buyer and disqualifying for a financed one.
• Lakefront and near-North condominiums. Assessments, reserve studies, and owner-occupancy ratios decide whether a unit is financeable at all. A pending special assessment often makes one a cash-sale candidate.

Foreclosure and Tax Sale Pressure in 2026

Illinois carries real foreclosure volume, but the Chicago area is not a national outlier. ATTOM recorded 12,533 Illinois properties with a foreclosure filing in the first half of 2026, 0.23% of housing units and the fifth highest state rate. The national count was 227,548, up 21% (ATTOM, July 16, 2026). No Chicago-area metro appeared among the ten worst metro rates in that report.

IHS read it the same way. Chicago-area foreclosure activity in July 2026 ran slightly below year-earlier levels in the metro, roughly equal in the city, and still below pre-pandemic levels (IHS, August 2026).

Property tax delinquency is the clock that moved. Public Act 104-0460 postponed the Cook County annual sale of delinquent tax debt from March 10 to December 1, 2026 and paused interest (Capitol News Illinois, February 26, 2026). Owners who read that postponement as forgiveness have the least room in December. Our guide to the Illinois property tax sale and its redemption clock walks the sequence.

What does the Chicago housing market 2026 mean if you need to sell?

It depends on your situation, because citywide averages hide very different outcomes. A 26.3% inventory decline and a 25-day average describe a clean, financeable house. Four common Chicago sellers do not own one.

The owner of a dated bungalow

Buyers shopping a $425,000 city median are looking at renovated stock. A 1920s bungalow with an original service panel, a clay tile sewer line, and an unfinished attic is shown against houses where that work is done.

Illinois disclosure rules add a timing detail sellers miss. The seller must deliver the Residential Real Property Disclosure Report before the signing of a contract (765 ILCS 77/20), and late delivery gives the buyer five business days to terminate. Selling as-is does not remove the form. It changes what goes on it, as our guide to Illinois seller disclosure requirements explains.

The heir settling a two-flat

An inherited Chicago building usually clears probate in the Circuit Court of Cook County first. Only a representative holding letters of office can sign the deed, and the Illinois small estate affidavit reaches personal property only.

Meanwhile the estate pays taxes, insurance, and utilities every month, and the October 1 bill does not pause for an open file. A firm closing schedule can be worth more to an out-of-state heir than a higher price.

The owner inside a foreclosure redemption window

Illinois forecloses through the courts, which leaves a homeowner more usable time than most states. A borrower may cure the default and reinstate within 90 days of being served or otherwise submitting to the court's jurisdiction (735 ILCS 5/15-1602). Redemption on residential property ends on the later of seven months from service or three months from the judgment of foreclosure (735 ILCS 5/15-1603).

A sale closing inside those windows can pay the loan off and preserve whatever equity is left, and with city prices up 13.3% there is often more than an owner expects. The full sequence is in our guide to stopping foreclosure in Illinois.

The landlord tired of a two-flat's tenant rules

An occupied building is a different product from an empty one, and Chicago's rules set the pace. The Residential Landlord and Tenant Ordinance does not cover units in owner-occupied buildings with six or fewer units (City of Chicago RLTO Summary, December 2023). A landlord who moved out of a two-flat is often inside rules they were once outside.

Notice periods apply to every residential unit regardless of RLTO coverage. Under the 2020 Fair Notice revisions, a landlord owes 60 days of notice to end a tenancy, decline a renewal, or raise rent for a tenant of six months to three years. That rises to 120 days past three years. A financed owner-occupant buyer usually wants the building empty, which is why an occupied three-flat sits. Leases can transfer with the building in a cash sale.

Where a cash offer from Propcash fits

Propcash is a direct cash homebuyer, founded in 2026 and based in Nashville, making offers as a principal rather than listing property for anyone. Sellers pay no fees or commissions, houses are bought as-is, and the seller picks the closing date. Illinois closings run through attorneys on both sides, so build in time for attorney review. Cash transactions can close in as few as 7 days once title and review are complete.

That route can fit a house with findings a lender would flag, an estate, a tax or foreclosure clock, or a tenant-occupied building. The useful move is to see both numbers together. Request an offer, set it beside a listing estimate net of repairs, commission, carrying costs, and the transfer tax above, then decide.

If listing is the stronger option, Propcash will say so and point you toward a local agent who fits. We may receive compensation from agents we refer. To see your options on a specific address, get a cash offer on your Chicago house at no cost. Our Chicago cash home buyer page and the Illinois cash buyer overview explain how the process works.

Frequently Asked Questions

What is the median home price in Chicago in 2026?

Illinois REALTORS reported a City of Chicago median sale price of $425,000 in July 2026, up 13.3% from $375,000 a year earlier. The statewide median was $338,000, up 6.0%, and the nine-county Chicago Metro Area median was $401,000. Those are midpoints of closed sales across all property types.

Why is Zillow's Chicago home value lower than the $425,000 median sale price?

The two numbers measure different things and should never be combined. Zillow's index models a typical value across the whole City of Chicago housing stock, whether or not a property sold, and read $337,993 on July 31, 2026. The Illinois REALTORS figure is the midpoint of what closed in one month, and two thirds of July's city closings were condominiums and townhomes.

How fast are houses selling in Chicago in 2026?

City of Chicago single-family houses averaged 25 days on market in July 2026, one day faster than a year earlier. Condominiums and townhomes averaged 19 days, seven days faster (Institute for Housing Studies at DePaul University, August 2026). Days on market counts the listing period only, leaving out preparation and the financed closing.

When is the Cook County second installment property tax bill due in 2026?

Cook County announced on August 18, 2026 that roughly 1.8 million second installment bills for tax year 2025 would be released September 1 and are due October 1, 2026. The first installment was due April 1, 2026. Illinois taxes are billed the year after the tax year, so a fall closing usually involves a prorated credit.

What does a Chicago seller pay in real estate transfer tax?

A Chicago seller's customary share is $2.25 per $500 of the transfer price. That is the supplemental CTA portion at $1.50 per $500 under Chicago Municipal Code 3-33-030, plus 50 cents to the state under 35 ILCS 200/31-10 and 25 cents to the county under 55 ILCS 5/5-1031. The buyer carries $3.75 per $500. On a $425,000 price the seller's share is about $1,913.

Does a cash sale make sense in the Chicago housing market in 2026?

It depends far more on the building and the seller's calendar than on the citywide median. Chicago inventory fell 26.3% in the year to July 2026 and single-family houses averaged 25 days on market, so a clean, financeable house often does well listed. A cash sale tends to fit a house with findings a lender would flag, an estate, a tax or foreclosure clock, or an occupied two-flat.
