You'll find the public notice of a foreclosure at http://www.GeorgiaPublicNotices.com. Please be mindful, however, that the foreclosure action associated with some of the properties shown there may have been halted.
Hope that helps.

Also, when a sale date is decided on a foreclosure it is posted on the clerk of court site (depending on where you live) and the newspaper.
