Illinois home prices 2026: Chicago booms, property taxes still win

You've found a listing in Chicago that looks almost reasonable next to what you remember paying two years ago, and then the seller's disclosure shows last year's property tax bill — a number that rivals a car payment on its own. Illinois carries the second-highest effective property tax rate in the country, and that one line item decides whether a home fits your budget more than the sale price ever will.

This page runs the real 2026 numbers for Illinois: what Chicago and a downstate market like Peoria actually cost once tax, insurance, and today's mortgage rate are added to the mortgage, what a first-time buyer can pull from the state's own down payment program, and whether a Chicago-area rental clears its bills for an investor once every real cost is counted. Illinois-specific figures below were last checked September 27, 2026.

Illinois housing market snapshot

Illinois's statewide median home price ran $328,632 in August 2026, up 4.3% year over year (Redfin). That number badly undersells what's happening in the state's dominant market: Chicago posted a median of $426,255 over the same period, up a sharper 9.3% year over year (Redfin, August 2026) — more than double the statewide growth rate, and the reason the state's headline number keeps climbing even though most of Illinois isn't anywhere near that hot.

Downstate tells a different story. Peoria's median sat at $148,000 over the three months ending May 2026, up a modest 2.0% year over year (Redfin) — less than a third of Chicago's price — while Springfield, the state capital, posted a striking 22.4% year-over-year jump to $186,000 in March 2026 (Redfin), a genuine spike measured off a low base rather than a sign the capital has caught up to Chicago-area demand. Statewide supply sits at 3 months (Redfin, August 2026), thin enough to keep sellers in control almost everywhere prices are moving.

Chicago's growth is anchored by a diversified job base — financial services and trading firms, tech employers like Citadel and Morningstar, and healthcare systems including Northwestern Memorial — that keeps demand steady even through years of Illinois's flat-to-negative statewide population growth.

So what for you: don't price-shop Illinois as one market — a Chicago-area budget needs a completely different plan than a Peoria or Springfield budget, and the statewide average isn't close to anyone's actual asking price in either direction.

Is Illinois a buyer's or seller's market?

Redfin calls Illinois a seller's market outright as of August 2026: homes are taking a median of 52 days to sell, selling for 99.2% of list price on average, and 35.8% are going for more than asking — all essentially flat to slightly up from a year earlier, with supply holding at 3 months statewide.

Chicago runs tighter still on some measures: a 49-day median time to sell, a 101.4% sale-to-list ratio, and 49.3% of homes selling above list price, which Redfin scores as "somewhat competitive" with a Compete Score of 63 out of 100 (Redfin, August 2026). Nearly half of Chicago listings are drawing competitive offers, a sharper number than the state as a whole.

Springfield's 22.4% one-year price jump suggests real downstate demand too, even if the sales-pace data there is thinner and less reliable than Chicago's.

So what for you: waived contingencies and over-ask offers are a reasonable expectation in Chicago proper right now, but don't assume the same urgency once you're pricing homes an hour or more outside the city — ask for the actual days-on-market and offer count on the specific listing, not the statewide number.

Can you actually afford a home in Illinois?

At Chicago's $426,255 median, 10% down, and this week's 7.03% mortgage rate — the 30-year fixed sits at a fresh high after the Federal Reserve's September 16, 2026 rate hike (Freddie Mac PMMS, September 24, 2026) — principal and interest alone run about $2,559 a month. Add Cook County's roughly 2.14% effective property tax rate for an owner-occupant with a homestead exemption (Ownwell County Tax Data, 2026), which adds about $760 a month, plus insurance and PMI, and the real payment comes to roughly $3,958 a month.

Insurance itself is a genuinely disputed number here. Insuranceopedia puts Illinois's average homeowners premium at $2,402 a year, but that figure is pegged to a specific $300,000 dwelling-coverage amount — well under Chicago's median home value. MoneyGeek puts the statewide average considerably higher, at $4,782 a year, which better reflects full replacement-cost coverage on a home Illinois's tornado, hail, and severe-thunderstorm exposure actually requires (WBEZ/Chicago Sun-Times, March 2026, on climate-driven premium increases). We use the higher, full-coverage figure — about $399 a month — in the math above, because a $300k-coverage quote would leave a Chicago buyer underinsured.

That $3,958 monthly payment requires roughly $169,600 in household income under the standard 28%-of-income rule — more than double Illinois's median household income of $83,390 (U.S. Census Bureau, 2020-2024 American Community Survey 5-year estimate). Strip the property tax out of the math entirely and required income drops to about $137,000 — still above median, but over $32,000 lower, which shows how much of Chicago's real affordability problem is the tax bill rather than the mortgage itself.

So what for you: at the state's median household income, a Chicago-area home only pencils out with a second income, a down payment well above 10%, or a search that includes Chicago's cheaper collar-county edges and downstate markets where the tax rate — and the price — is lower.

Illinois cities to watch

Chicago sets the state's price ceiling and its pace, backed by financial services and trading firms, tech employers like Citadel and Morningstar, and healthcare anchors including Northwestern Memorial. It's also where Illinois's property tax problem is sharpest, especially after a Cook County township reassessment.

Naperville, a western suburb known for its schools, posted a $654,567 median in August 2026, up 4.7% year over year (Redfin) — the trade-off for that price is a well-established commuter town rather than city living.

Evanston, home to Northwestern University just north of the city, ran a $504,666 median in August 2026, essentially flat, down 0.31% year over year (Redfin) — one of the few Chicago-area markets that isn't currently accelerating.

Peoria, anchored by Caterpillar's global headquarters, OSF HealthCare, and Methodist Medical Center, is Illinois's affordability outlier at a $148,000 median — less than a quarter of Naperville's.

Springfield, the state capital, runs on government employment and just posted the state's sharpest one-year price move, up 22.4% to $186,000 (Redfin, March 2026), though off a low enough base that it remains one of the more affordable state-capital markets nationally.

So what for you: Naperville and Evanston buy you Chicago-area jobs and schools without Chicago proper's price ceiling, but not its property tax bill — Cook County and the collar counties both carry high effective rates, so check the specific county rate before assuming a suburb is the cheaper move it looks like on price alone.

Rent vs buy in Illinois

A 3-bedroom rental in Chicago runs about $2,800 a month on average, with 2-bedrooms at $2,500 and 1-bedrooms at $2,195 (Zumper, September 2026). Against the roughly $3,958 monthly cost of buying at the median with 10% down calculated above, renting a comparable 3-bedroom comes out about $1,158 a month cheaper before counting any equity you'd build by owning.

That gap is driven almost entirely by Cook County's tax rate and today's 7.03% financing cost, not by the sale price itself — a buyer putting more down or finding a lower effective county tax rate narrows it meaningfully, but doesn't erase it at current rates.

So what for you: run your own numbers with the specific property's actual county and township tax rate before assuming buying beats renting on a pure monthly-cost basis in the Chicago area right now — the rent-vs-buy gap here is wider than in most states we've covered, specifically because of the tax line.

First-time buyers in Illinois

PMI is unavoidable below 20% down on a conventional loan — on the math above, that's roughly $240 a month at 90% LTV, within the $115–$375 monthly range USMI reports for a loan this size depending on credit tier (USMI, 2026). It's temporary, similar to the example in our guide to canceling PMI early, and disappears once you cross 20-22% equity.

Illinois runs one of the more generous state-level down payment programs in the country: IHDAccess Home, launched March 2026, offers up to $15,000 in down payment and closing-cost assistance as a zero-interest second mortgage with repayment deferred up to 30 years, unless the home is sold or refinanced sooner (Illinois Housing Development Authority, via NCSHA, March 2026). Income limits vary by county — Cook County caps out at $137,885, Sangamon County (Springfield) at $131,905 — and the program requires mandatory pre-purchase counseling but runs through more than 160 approved lenders statewide. That's on top of the roughly $18,000 in average assistance that goes uncollected nationally by buyers who never check what they qualify for, and our breakdown of how down payment assistance actually works covers how to stack programs without one disqualifying another.

So what for you: check IHDAccess Home eligibility before assuming you need the full 10% down in cash — $15,000 covers more than a third of that down payment at Chicago's median, making it one of the largest state-run grants in this series.

Real estate investors in Illinois

Chicago is Illinois's toughest investor market once the property tax line is included, and it's gotten tougher since our own spotlight ran the numbers in July. At 25% down and this week's 7.03% rate, PITI on the $426,255 median runs about $3,312 a month, including Cook County's roughly 2.20% effective rate for a rental without a homestead exemption (Ownwell County Tax Data, 2026). Against a 3-bedroom rent of $2,800 (Zumper, September 2026) less an 8% management fee and 5% vacancy allowance, effective rent comes to about $2,436 — a shortfall of $876 a month before maintenance. Add the 1.5%-of-price maintenance reserve applied across every state in this series and the real number runs close to negative $1,409 a month, notably deeper than the negative $998 our own Illinois investor spotlight found in July, because both the price and the rate have climbed since, and insurance is now being priced closer to Illinois's real storm-exposure cost rather than a lower generic estimate.

Peoria was the one market that spotlight found clearing breakeven, at a reported $58 a month in positive cash flow. Rerunning it at today's rate and with the standard maintenance reserve applied flips that to roughly negative $168 a month — small, but no longer positive. At 25% down on Peoria's $148,000 median, PITIA runs about $1,157 a month against roughly $1,350 in rent (PropertyPundit's Illinois spotlight, July 2026, citing Zillow Rental Manager), before the maintenance reserve takes the last of the margin.

That means no market checked in this analysis currently clears positive cash flow in Illinois at today's rate — a materially worse picture than three months ago, and not one an investor pitch on Chicago tends to mention. Our DSCR loan investor guide covers how lenders calculate the ratio Peoria now barely misses, and our county-by-county SFR yield map is a faster way to check whether a market outside Illinois clears the bar instead.

So what for you: don't underwrite an Illinois rental on a spotlight article's numbers from even a few months back — rerun the maintenance reserve and this week's mortgage rate yourself, because both have moved against Illinois investors specifically, and Cook County's reassessment risk means the tax line can move against you again after closing.
