This is the link for the Specialized Searches section of http://www.BestGeorgiaHomeSearch.com . Once there, you can click on the county name, which will show you foreclosed properties in that county (you can sort by price, subdivision, city, etc). There are even a few special HUD-only links, if you scroll down through the page.
I did a blog post on this. Try this search feature on Google. Here are the steps.
1. Visit Google Base http://www.google.com/base/
2. Select Housing
3. Enter the city and state you want to find forclosures in. Enter in the search bar. Hit enter
4. Where it says listing type. Select foreclosure
You should see listings of foreclosures in the city and state you want to find foreclosures in. Hope this helps.
