| rshen-ga,
Thanks...those PINs did the trick in terms of allowing me to confirm
the effectiveness of the search tool I located.
Liens, as you know, are "recordable documents" that are kept on file
in Cook County government offices.  In the past, this meant a trip to
the county courthouse to examine the records.  But these days, many
such records are available on the internet.  Much of the information
is available at no charge, and the actual liens can be downloaded for
only a nominal fee.
First off, for the PINs you provided, here is what I found:
==========

So that last property seems to be free of liens, as far as the online
record-keeping shows.
These reports are available at:
http://www.ccrd.info
Cook County Recorder of Deeds (CCRD) 
Simply click on "PIN Search" in order to get to the proper search
form.  Enter the PIN of interest, and you'll quickly pull up a record
similar to the ones above.  If you click on the highlighted texts in
the record, you can retrieve additional information.  Clicking on the
document number itself will take you to an option for downloading an
actual copy of the lien (or other documents) for a small fee.
It's also possible to approach a lien search from another direction,
and see all recently-filed liens, if that is of interest.  Just click
on "Document Number Search" and on the search page that appears leave
the "Document Number" field blank.
On the "Document Types" pull-down menu, select the type of document of
interest (Note that there are several different types of liens listed
-- Claim lien, Mechanics lien, Tax lien, etc, along with a simple
"Lien" heading...you probably need to search these all to see a full
list of recent filings).  Select the date range of interest, and
you'll get yourself a list of all liens filed within those dates.
One last thought.  It may well be possible to arrange with the CCRD a
bulk search, since you're dealing with 1,000 PINs a month, or so. 
This would involve you providing them the list of PINs in a
predetermined format, and they would provide all the relevant records
in downloadable form.  It's worth contacting them directly to see if
this option is available.
I trust this information fully answers your question.  However please
don't rate this answer until you have everything you need.  Just post
a Request for Clarification to let me know if I can assist you
further, and I'm at your service.
All the best,
