Check out Bob's Sunday real estate column in the Chicago Tribune (available online now), where he breaks the news of former Chicago White Sox and Chicago Cubs pitcher Neal Cotts taking a big loss on his condominium unit in Chicago's River North neighborhood, which he just sold for $307,000 after paying $375,000 for it in 2004. Bob also breaks the news of former Tribune Co. Chairman and CEO Dennis FitzSimons paying $2,625,000 for a penthouse condo unit in the Park Tower building on Chicago's Gold Coast.

And, Bob also breaks the news of actor Vince Vaughn finally renting out his longtime town home in Chicago's River North neighborhood at $7,000 a month.

The column also features news previously reported here as a breaking-news alert earlier this week about former McKinsey & Co. executive Julian C. Mack, who until recently led all of McKinsey's Midwestern offices, listing his mansion on Lake Michigan in Winnetka, Ill. for $6,400,000.
