looking for properties that are NOT on MLS Listings

[Babe Savage]

hello All

I am searching for another way of finding properties that are not on the MLS LISTING. I am in the Atlanta area and I'd like to find houses to rehab but whenever I search on the MLS LISTING...the next day I call and the property is pending. I've heard of code enforcement houses but I'm not sure where to find out about them. I also see houses that are boarded but no luck in finding out about them either...HELP PLEASE... IF POSSIBLE
