Commercial/mixed use properties mls/listings in Chicago?

[Rob Patel]

Hi there and thanks in advance for your help.  I've invested in a few condos in and am looking to move into a mixed use (2-3 units with a commercial space in the ground floor) property.  I've used Redfin in the past for my condos, but there aren't too many listings that fit this new profile on there, and while I've found some listings on loopnet, so many are hidden/locked to free members and I can't believe how exorbitant the membership cost is to view those.  Is there no free (or cheaper) mls for commercial properties like this?  Thanks!
