You can try to figure out the address by driving to the area & try to figure it out which house it is.
Once you have that you can try to search for it on the cook county assessors office website by doing an address range search. If it is a SF home there will be no assessments unless you mean tax assessments, which you can then look up on the treasurers office website.
P.S. Your best bet is to always work with a buyers agent. We do all the work for you.
