Ishbia, 43, whom Forbes recently listed as one of the 20 wealthiest people in Illinois, with a net worth of $3.4 billion, is linked to trusts that are behind the purchase of a portion of the Winnetka site as well as a $36 million mansion in Naples, Florida, that was bought in January. A building permit filed April 1 in Collier County, Florida, in connection with the Naples mansion identifies Ishbia as the owner.
