Will county joliet property owners information

[Nathan Waters]

I recently decided to start driving for dollars to find my next investment. I found quite a few homes of interest but I haven't put together a plan for contacting motivated sellers. Most of the houses were vacant with stickers in the window banning occupancy. Any advice on the best way to find the owner? Forwarding address? Phone number? I could harass my real estate agent for some of the info, but I hate to bother him on an off market deal since he won't be getting commission. Anyone have advice or experience specific to will county illinois?
