Does living on the top floor of most high-rises still feel like living in the basement? Chicago’s 100-story John Hancock Center will change all that. Whereas the tallest residential home in Dallas is a 42nd floor penthouse, the Hancock’s condos don’t start until the 44th floor and continue all the way to the 92nd floor. Completed in 1969, the Hancock Tower is one of the most recognized buildings in Chicago and offers up some surprisingly inexpensive homes with incomparable city and Lake Michigan views.
