A group led by real estate investor Paul Gearen is looking to sell a six-story office building in Chicago for $100 million, Crain's Chicago Business reported, citing a source with knowledge of the sale.

The 575,000-square-foot building at 801 S. Canal St. is leased to Northern Trust Corp., a financial services company based in the city. That lease will end in October 2020.

The property is being marketed by HFF.
