The Chicago MLS is called the MLSNI (multiple listing service of northern Illinois). You may notice that your search does not include all listed properties. The MLS only allows limited viewing of properties without registering with a user name and password. Register now and see up to 50% more properties that meet your search criteria. You will be able to see all the listings for homes in your target profile as well as enhanced property information.

This site will show you all the mls listed properties by brokers in Chicago (or at least 95%+ of them as some real estate brokers will only allow buyers to view properties once they have registered).
