Parts one and two
A Burnham tower Brookfield bought for $306 million just sold for $41 million
Twenty-nine dollars a foot for a full Loop block. Nothing about the building failed.
Chicago · The Loop · 15 September 2026
There is a building on Jackson Boulevard that takes up an entire city block, sidewalk to sidewalk, Jackson to Van Buren.
Daniel Burnham’s firm drew it. It went up in 1912, with an addition in 1927. They called it the Insurance Exchange. Twenty-two stories. About 1.4 million square feet. The floors are wide, close to 70,000 square feet each, which is exactly why trading firms wanted them, because you can put a lot of people in one room and see all of them. Wolverine Asset Management worked in there. So did Enova. So did the Chicago office of the Securities and Exchange Commission. There is a garage underneath that holds 240 cars and 46,000 square feet of storefront at the street.
On the last day of January, it sold for $41 million.
$29
a foot.
That is what $41 million comes to across 1.4 million square feet. You could not build a parking garage for twenty-nine dollars a foot. You could not put in the elevators.
How It Got There
In 2018, Brookfield paid $306 million for it. That was about $218 a foot. Then they spent roughly $24 million more fixing it up.
They borrowed $280 million to do it. That loan did not stay in one place. It was cut into pieces and sold to investors as bonds. The same way a mortgage on a house gets bundled and sold. Once that happens, the bank that made the loan is not the one holding it anymore. Strangers hold it.
In 2022 the foreclosure was filed. A company called a special servicer took over the file, the outfit that gets paid to manage a loan after it goes bad, and ran it for four years. In January of this year it was sold to a New York partnership for $41 million.
The repair job alone came to almost 60 percent of what the whole building later sold for.
The Loan Was Bigger Than The Price
The buyers borrowed $58.5 million to buy a $41 million building. Thirty-three and a half million went to the purchase. Twenty-five million was set aside to pay for filling it up.
The market is saying the building is not the expensive part. Filling it is. It was 47 percent leased.
That is a low basis and a lender paying for the upside. Lease it from half full to mostly full and the building is worth a multiple of the price, and almost none of the money at risk belongs to the buyers.
Nothing Physical Failed
The steel is fine. The block is still a block. The floor plates are the same ones the traders wanted. Nobody torched it and nothing fell down.
What collapsed was an arrangement. Made in another city, by people who never worked a day in the building, about a number they wrote down in 2018.
The $41 million is not what a Burnham landmark is worth. It is what is left after a $280 million loan goes bad, a servicer runs the clock for four years, and the bondholders take the haircut. It is a settlement. It is not a price.
It Is Not One Building
On the ninth of June, the same New York firm that bought Jackson defaulted on a $343 million loan on One South Wacker. Forty stories, 1.2 million square feet, two blocks from the Willis Tower, renovated in 2020.
That tower is 73 percent occupied. The payments were current. It did not fail because it was empty. It failed because the loan came due and nobody would write a new one.
27%
Downtown office vacancy, mid-2026, per CBRE. And of the office loans that came due in this metro between 2020 and 2023 and had been bundled into bonds, 43 percent defaulted, were seized, or went to foreclosure. Downtown's office construction pipeline is at zero for the first time since 2012.
Default Is Not Failure. It Is A Position.
The same firm handed back One South Wacker in June and bought 175 West Jackson in February. It owns the Old Post Office. It owns the Aon Center, where roughly $678 million comes due. It is fighting foreclosure at the Civic Opera Building.
In that business you give back the one where the old number can’t be fixed, and you buy the next one at the new number. The building does not care. The loss goes to whoever is holding the paper.
So Who Is Holding It
Somebody owned those bonds on 175 West Jackson. Pension funds buy that paper. So do insurance companies and bond funds. It is ordinary, boring, supposed-to-be-safe investing.
The broker got paid. The servicer got paid, for four years, either way. The lawyers got paid.
Nobody has printed the list of who held the bonds. That is a thing that can be found out, and it has not been.
The lazy version of this is that downtown is dying. Downtown is not dying. Downtown is simply changing hands.
Part two is about where the bill for that goes, because it does not stay downtown.

Part two of two
Where the bill goes
Nobody in Gage Park signed that note. They will pay part of it anyway.
Chicago · Cook County · 15 September 2026
Here is the part that never gets explained in plain words. It is four steps and it is not complicated. One. The city, the schools and the parks decide how much money they need. That is called the levy. The levy does not care what your building is worth. It is a dollar amount.
Two. The county assessor puts a value on every property. Your share of the levy is your value divided by everybody’s value.
Three. Owners can appeal that value to the Cook County Board of Review. Three elected commissioners who can cut it. Big commercial owners appeal every year, with lawyers who do nothing else. Most homeowners never appeal at all.
Four. Here is the whole thing. When the Board cuts a downtown tower’s value, the levy does not go down by a single penny. The pot still has to be filled. So everybody who did not appeal pays more. That is it. That is the pipe.
What It Moved
A study by a University of Chicago professor found that the Board of Review has been shifting 3 to 4 percent of the tax base onto homes every single year through commercial appeals. Enough to cancel out the assessor’s work on the residential side.
The assessor’s office put it in dollars a homeowner can feel: against about $9 billion billed in Chicago property taxes, those cuts shifted roughly $700 onto each Chicago homeowner in one year.
Some of the cuts granted: Trump Tower, 39 percent. A Hilton, 33 percent. A luxury high-rise on South Michigan, 32 percent. A data center, 22 percent.
16.7%.
How much Chicago's median home tax bill rose last year, to $4,457. The largest jump in at least thirty years, and the third straight year above 15 percent. Taxpayers were asked for $872 million more.
Now hold that next to the number in every headline about City Hall: the projected 2027 budget gap is $882.4 million.
They are the same size. One of them is a crisis on the evening news. The other one already happened, quietly, in an envelope.
The Board’S Side, And It Is Not Nothing
The commissioners say the commercial properties were assessed too high to begin with, and that the assessor’s methods were unreliable. With Loop values genuinely falling off a cliff, that argument gets stronger, not weaker. Every downtown owner now has a real case.
Which is the problem. The largest transfer of tax burden from downtown onto the neighborhoods in modern memory is about to be authorized, and every step of it will be defensible. Nobody has to do anything below board. The forms are all filled out correctly.
The chairman of the Board of Review is George Cardenas. He is running for mayor. He is also on the ballot in November to keep the board seat. Twenty years ago, as an alderman, he abstained on the seventy-five-year parking meter lease and said he did not have the numbers to decide.
Now he is the one holding the numbers.
The Voters Already Moved
In March, the sitting county assessor lost his primary. He performed worst exactly where tax bills rose the most. The wards that got hit hardest threw out the man who was trying to push the burden the other way, and elected a challenger slated by the county party.
Conceding, the outgoing assessor said the appeal system itself is a legacy of machine politics. He had spent the campaign pointing out that his opponent takes money from property tax attorneys. The exact profession that makes its living at the Board of Review.
The Second Hit, Which Nobody Has Named
Tax increment financing (TIF) freezes a district’s value at a base number. Everything above that base, the increment, goes into a TIF fund instead of to the schools and the city. Here is what happens when values fall. The increment is not a percentage. It is the difference between today’s value and the frozen base. When downtown values collapse, the increment does not shrink a little. It can go to nothing.This already happened here once. After the last crash, the LaSalle Central district downtown went from generating about $20 million to generating zero, in two years. Now look at what is stacked on that today. The school district passed a budget counting on $285 million in TIF surplus the City Council has not voted, plus $150 million from Springfield that nobody promised. A large share of the city’s increment is downtown. If Loop values take a steamer, the Council can vote the sweep and the money will not be there to sweep. The district’s own fallback is a mid-year hiring and spending freeze starting after December 31. That is January. That is seven weeks before the election.
Why It Cannot Be Fixed By Waiting
The levy is driven by pension payments that are set by state law and go up every year. The base is set by a market that is going down. When those two move in opposite directions, the rate has to rise, and the rate lands on whoever did not appeal.
Both ways out make the base smaller. Turn an empty tower into a data center and it gets assessed favorably. One already took a 22 percent cut on appeal, and in the north suburbs that class of property has been assessed at roughly two-thirds of market value after appeals. Turn it into apartments with public subsidy and you freeze more value out of the general pot.
What It Is Not
It is not a death spiral, and anybody selling you one is selling you something.Twenty-nine dollars a foot is how a market clears. A buyer at that price can charge rents nobody else can match, which is how a downtown actually refills. Chicago is third in the country for people coming back to the office. No new office buildings are going up, which is the ordinary setup for a recovery.The trouble is the clock. Repricing takes a quarter. Refilling takes a decade. The pension payment is due every year in between. The damage arrives long before the recovery does, and somebody covers the gap while everyone waits.
What It Is
It is leverage.
Financial leverage, for the buyers with a fifty-eight-million-dollar loan against a forty-one-million-dollar building. And political leverage, because a broken downtown is the argument for everything. The stadium bill, the tax breaks, the subsidy, the new campus, the pro-business mayor. Nobody has to make a shady ask. They just point at 27 percent and say there is no choice. The building at 175 W. Jackson did not fail. The paper on it failed. And the difference between what that building is and what its paper was worth is going out this year in envelopes, to people who never heard of it.
Who made theirs. Who covers it.
The record
- Christopher Berry, University of Chicago Harris School, An Evaluation of Progress on Residential Assessment Fairness in Cook County. On the Board of Review shifting 3 to 4 percent of the tax base to residential annually.
- Cook County Assessor’s office statements and data dashboards, December 2025. The roughly $700 per-homeowner shift, and the individual cut percentages cited.
- Cook County Treasurer’s office. Chicago median residential bill of $4,457, a 16.7 percent increase, and $872 million in additional taxes billed.
- City of Chicago 2027 Budget Forecast, released September 3, 2026. The $882.4 million projected gap.
- Chicago Board of Education FY2027 budget, as amended July 30, 2026. The $285 million TIF surplus assumption, the $150 million state assumption, and the mid-year freeze contingency.
- Cook County Clerk TIF district reports, including LaSalle Central, for the post-2008 collapse in increment.
- Illinois State Board of Elections filings. County assessor primary, March 17, 2026.
- Cook County Board of Review published decisions and appeal records, 2022 to present.
- Two things in this piece are contested and are labeled as such: the assessor’s office and the Board of Review disagree publicly about whose numbers are right, and both were given their argument here. Where a figure comes from one side of that fight, the piece says so.
