Yes, depends on the location and the type of unit. There are 77 census tracts and over 220 neighborhoods in Chicago. There are at least 4 types of homes in each neighborhood and so about 880 different markets that all could be heading in different directions. $250,000 2br in Lincoln Square could be trending differently than $400,000 1br in River West.
If you have a specific type of home in a specific neighborhood I should be able to provide you with some trends.
