The Cannons bought the site in 2006 for $19 million, which Crain's Chicago Business reported was the most expensive home purchase in the area at that time. The Cannons say they made all their monthly payments on a one-year loan. But, they say, when the lender, Amcore Bank, insisted they pay off the loan in one year, rather than renegotiating a long-term loan, as expected, the Cannons couldn't do so and the bank foreclosed.
