You may have to pay for the information at many sites and it may not be as detailed as you want when you get it.
I can search for you if you want. The Realtor MLS is an easy tool to use, if you are in contact with a Realtor that knows how to use it to your advantage. Some of the best deals are not even on foreclosures right now, so you may not want to limit your search that way......
I am in West Chicago a couple times a week and know it well.
Let me know if I can help you....... more
