Here in Massachusetts the Registry of Deeds, of which most are online, offer the ability to search for "Order of Notice's" which are code for Pre-Foreclosure notices. Once foreclosed, "Foreclosure Deeds" are recorded and then there is a wait until the Bank actually puts the property out for sale.
Look for Short Sales as these are often attempts to sell pre-foreclosure. Also consider your local REO specialist Realtor(r) as they will have the ability to filter listings by Short Sale and Foreclosed status.
Good luck, and hope your warm down in Thomasville, GA
