I'm coming up with slightly different numbers than Simir. Just looking at the following types of properties;
single family homes
I'm showing about 24,995 active listings available for sale in the Multiple Listing Service in the City of Chicago as of right now.
Are you interested in simply researching local markets or are you looking for information in anticipation of purchasing something?
I might be able to provide a more helpful answer to you if we can narrow the question that you're asking slightly.
Let me know if I can be of further assistance.
