Equity Commonwealth is in the late stage of talks to sell Groupon Inc.'s headquarters in Chicago to real estate developer Sterling Bay for more than $515 million, The Wall Street Journal reported, citing people privy to the matter.
The roughly 1.6 million-square-foot property at 600 W. Chicago Ave. was put on the block earlier in 2017, with Eastdil Secured hired to market the property, according to the publication.
