One house. One owner. Forty-five years. Illinois.

★★Once to the bank. Three times to the state.★★

Median Illinois home Official rates only Every step shown

On August 20, 2026, Crain's Chicago Business reported that Illinois is the easiest state in America to afford a house. The underlying study, published by Visual Capitalist from MoneyLion data, found the typical Illinois household earns $20,002 more than it needs to buy the median home. The largest surplus in the country. "The most breathing room in their household budget."

The study did not count property tax. It did not count insurance. Illinois has the highest effective property tax rate in the United States. Here is what happens to the breathing room when the two missing bills are put back, using the study's own rule that essential expenses stay under half of income:

Surplus, as published +$20,002 Property tax, median IL home, 1.84% $6,328 per year Homeowners insurance, IL average $2,592 per year Income required at the study's 50% rule: 2 x ($6,328 + $2,592) = $17,840 Surplus, corrected +$2,162

$20,002 of breathing room becomes $2,162. That is $180 a month. The crown survives by ninety percent less than advertised, and it survives only until the bills start growing. They have never stopped.

The bills grow. The county measured how fast.

The Cook County Treasurer's 20-Year Property Tax History, the county's own study of its own billing records, measured what happened from tax year 2000 to 2019: Chicago residential taxes billed rose 164%, which is 5.2% compounded every year, against a 36% rise in the cost of living. Suburban residential rose 116%. Individual wards rose 400 to 500 percent. This is not a projection. It is the receipt.

Now buy the median Illinois home, $343,923, with 10% down at the 2026 average mortgage rate of 6.35%, and hold it for 45 years, one working life. Grow the tax bill at the rate the county itself measured. Count every dollar and who receives it:

To the seller, once

$343,923

the house itself, the only payment that buys the asset

To the bank

$383,833

mortgage interest over 30 years. 1.1x the price of the house. Then it ends.

To the state and its taxing districts

$1,069,502

property tax over 45 years at the county's measured 5.2% growth. 3.1x the price of the house. It does not end.

To the insurers

$551,431

premiums at 6% annual growth, the national 2012 to 2026 pace

$2,348,690 paid. $343,923 of house owned.

The bank is paid once and leaves. The state charges the price of the house a first time by year 27, a second time by year 38, and a third time by year 45, and then keeps charging. The mortgage has an amortization schedule. The tax has no final payment.

Cumulative payments on one Illinois house, by year

Interest ends at year 30. Tax and insurance do not end at all. The dashed line is the price of the house; the tax line crosses it three times. Hover any point for values.

The 45-year property tax total at each growth rate the record supports. All rates from the Cook County Treasurer's study except the zero row, which assumes the bills freeze today and is contradicted by every decade on file.
Growth assumption	Measured where	45-year tax total	Times the house price
0%, bills frozen forever	nowhere, ever	$284,768	0.8x
4.1% per year	suburban Cook residential, 2000 to 2019	$787,062	2.3x
4.6% per year	countywide residential, 2000 to 2019	$890,948	2.6x
5.2% per year	Chicago residential, 2000 to 2019	$1,069,502	3.1x

Say the whole thing plainly.

The state's flagship business paper crowned Illinois the easiest place in America to afford a house, on a study that omitted the largest housing bill Illinois charges. The same governments that collect that bill have grown it at two to three times inflation for as long as records run, and the county's own treasurer published the receipts. Both things are presented to the same residents in the same year: you have the most breathing room in America, and the bill that consumes it is the fastest-compounding one you pay.

A resident who takes the headline at face value buys the house. The house then costs its own price once to the seller, once more to the bank, and three times to the state, with the state's meter still running when the other two have been paid in full and gone. If a private company sold a $344,000 product with a mandatory, perpetual, compounding 1.84%-of-value annual fee, the fee would be the story. Here, the fee is the omission, and the omission wears the crown.

Every assumption, so you can check it

Median Illinois sale price $343,923: Redfin, June 2026, closed sales.
Effective property tax rate 1.84% of market value, highest of all 50 states and DC: ATTOM via Bankrate, tax year 2024.
Insurance $2,592 per year: Insurify Illinois average, 2026, $300,000 dwelling coverage. Grown at 6% per year, the national 2012 to 2026 compound pace (III through 2021, Insurify to 2026).
Mortgage: 10% down, per the study's own assumption; 6.35%, the Freddie Mac average of all 26 weekly readings, February to July 2026; 30-year fixed; interest computed from the full amortization schedule. Mortgage insurance excluded here; including it adds about $14,000 more.
Tax growth 5.2% per year: Chicago residential taxes billed, $1.33 billion to $3.51 billion, 2000 to 2019, Cook County Treasurer's 20-Year Property Tax History. The alternative rates in the table are from the same study.
Surplus correction: the study's published $63,388 income requirement plus the two omitted bills divided by its own 50% essentials cap. $63,388 + 2 x $8,920 = $81,228 against $83,390 income, per the study's published state table.
Honest limits: growth is extrapolated from a Chicago-measured rate onto a statewide median home; taxes here are nominal dollars, not discounted, and wages also grow; the crossing years shift with the rate chosen, which is why the table above shows all of them. At the suburban rate the state collects the house 2.3 times instead of 3.1. There is no published rate at which it collects less than the bank does.
