The King of Liens

By The Briefcase Team | May 20, 2026

On May 11, a federal judge ruled that Cook County is on the hook for about $15.4 million a year to homeowners whose equity it unconstitutionally seized through its tax sale system. The decision affects an estimated 1,700 to 2,500 families who lost an average of $70,000 each in equity over tax debts that, in some cases, ran as low as $1,600.

Almost nobody has connected that ruling to the man who allegedly built a $25 million Chicago property empire by gaming the same system from the other end. Meet Greg Bingham. He has not been charged with anything. He is still operating his storefront in Northlake. And researchers inside the Cook County Treasurer's office have spent two years telling federal and county prosecutors that he allegedly ran a "widespread and sophisticated conspiracy to commit millions of dollars in fraud."

Pour something strong. We are going in.

Bingham's companies allegedly used duplicated photographs of a pink window frame, a cluttered living room, and a moldy hallway to claim that dozens of separate properties had been "substantially destroyed," triggering refunds from Cook County under a state law called the "sale-in-error" provision.

That law exists for a reason. If you buy a tax lien on a property at auction and the property is later found to be owned by a church, or has an active bankruptcy, or got destroyed in a fire between auction and possession, you can unwind the sale and get your money back, sometimes with interest. The state of Illinois has one of the most generous versions of this rule in the country. Judges have undone sales over a 3-cent rounding error and a misspelling of "Greenwood" as "Greemwood."

Treasurer's office researcher David Lighty alleges Bingham figured out how to weaponize that generosity. Between 2015 and 2022, Bingham's companies got more than $95 million in refunds, including $7.8 million in interest. From 2018 to 2024, Lighty's team identified 145 refunds totaling more than $3 million that appeared to use duplicated or doctored photographs to qualify under the "substantially destroyed" provision.

Court records show that in January 2024, Bingham obtained a $170,000 refund for a building in Chicago Heights by filing photos of a "mold-infested wall," a "hallway with paint chips on the floor," and a bathroom with a distinctive pink bathtub, sink, and window frame. Bingham filed a sworn affidavit saying he took the photos in November 2023.

The same photos, with different dates stamped on them, had already been used to claim refunds on four other unrelated properties going back to 2018.

About a month after approving the Chicago Heights refund, Judge Kathleen Marie Burke approved a separate $14,000 Bingham refund using what investigators say was a "cropped and rotated version" of the same pink window frame. Judge Maureen O. Hannon approved two refunds in the same week using photos of "the same cluttered living room."

Bingham's companies allegedly filed 145 of these. Almost a dozen sitting Cook County judges allegedly signed them. To borrow from the man's own historian, Andrew Kahrl of the University of Virginia: "The courts don't do any scrutiny at all. The judges are just pushing papers along."

The photograph play is the flashy one. The expensive one is more interesting.

Lighty alleges that on at least three occasions, Bingham bought a property's delinquent taxes at auction through one company, then bought the property itself through a separate shell company. The shell would then file for bankruptcy. Bingham's first company would then claim a refund under the sale-in-error provision that grants refunds with interest for properties "tied up in bankruptcy proceedings, even if the bankruptcy petition was filed after the tax sale had already taken place."

He kept the property. He got the tax money back. He got interest on top. According to Lighty's memos, this single maneuver pulled in nearly $235,000, including $47,000 in interest.

This is the part where you start to admire the engineering, briefly, before remembering who was paying.

The Cook County Treasurer's research unit calculated in 2022 that the sale-in-error loophole, across all tax buyers, siphoned nearly $280 million from "schools, parks, libraries, fire departments and other government agencies." The money for refunds comes out of the budgets of those agencies, with up to 54 percent interest tacked on. When Bingham's company allegedly got $7.8 million in interest payments between 2015 and 2022, a school district somewhere wrote that check.

On the other side of the same story, you have the homeowners. Lighty's investigation overlaps with a separate Injustice Watch / IPRE analysis showing that more than 1,000 owner-occupied homes in Cook County were taken through tax foreclosure since 2019, including 125 owned by seniors. Federal Judge Matthew Kennelly's May 11 ruling in Bell v. Pappas now obligates Cook County to find $15.4 million a year, indefinitely, to compensate them.

So we have a system that:

The Cook County State's Attorney's office told reporters in March that its inquiry into Bingham was "still a pending investigation." A separate Injustice Watch reporter has now been writing about this guy since 2022. The FBI has Lighty's PowerPoint presentation. Greg Bingham still has a storefront in Northlake. The court system that allegedly stamped through his refunds is the same court system that will now process restitution claims from the homeowners those refunds were funded by.

Free markets need three things to work: clear rules, honest documentation, and courts that read what they sign. Tax-lien investing is a legitimate business. Somebody has to put up the cash for delinquent property taxes so schools get paid on time. The market for that risk should price itself fairly.

The Cook County system did not fail because tax-lien investors exist. It failed because the rule book was written with one safety net for investors (sale-in-error refunds with interest) and a different one for homeowners (a thinly funded "Indemnity Fund" most never apply to). It failed because almost a dozen judges allegedly approved refunds without checking whether the photographs in front of them were the same photographs they had approved last month. And it failed because, by Lighty's count, six attorneys filed 80 percent of those refunds, two of whom (Douglas Miller and Heather Ottenfeld) handled the bulk, and nobody appears to have asked any of them anything.

A real market for distressed property requires courts that audit. Cook County didn't have those courts. Whether one investor named Greg Bingham allegedly built a $25 million empire in the gap is the test case for whether we're going to fix that.

Bell v. Pappas damages. Both sides were ordered to submit case plans this week. If they can't agree, the judge writes the framework. The $15.4 million annual number could expand if more homeowners come forward.

The Cook County State's Attorney's office. It has had Lighty's memos for nearly two years. Eileen O'Neill Burke ran on transparency. The clock is ticking.

Illinois state legislation. Tax sales are paused statewide until December 1, 2026, while lawmakers rewrite the system. Whether the new law fixes the sale-in-error loophole or leaves it for the next Bingham will tell you whether Springfield learned anything.

Greg Bingham allegedly ran a $95 million refund operation in plain sight, using the same photographs, with a small group of judges signing off, while Cook County simultaneously seized $108 million in equity from 1,000 mostly senior, mostly low-income homeowners over tax debts as low as $1,600.

One side of that ledger has been ruled unconstitutional by a federal judge.

The other side has not been charged with anything.

We are watching the result of two decades of legislative inattention curdle into a single, scandalously instructive case. The pink window frame deserves a museum. The system that approved it 145 times deserves a rebuild.
