If you have trouble confirming the information based on what Tim said, please feel free to contact me. I am very familiar with Fairburn and Fulton County. I am happy to assist you with getting this information. I will need your address, and I can take it from there.
Check your county clerks office. There will have been a new deed if the bank foreclosed. Did you ever see foreclosure documents nailed to the property as a notice of pending foreclosure? They have to do that. How do you know it was foreclosed (or sold as you called it)?
