Chicago area real estate statistics for residential and commercial properties have been updated for the past twelve months ending in Oct 2011. http://realtyevolved.net/residential-commercial-distressed-chicago-real-estate/
Contracts written is up for both residential and commercial properties. Months supply of inventory is also lower, although for several property types the drop has been consistent for the past few months. However, market time is on the rise across the board.
With the winter season just around the corner, it will be important as to whether contracts written as well as sales can continue.
