Does anyone have any recommendations for a good preforeclosure list service or advice on where to get good data?

Hi @Kathryn C. Which specific Georgia counties were you looking for?

Also, how "pre-" do you need the data? The Notice of Sale Under Power (the "foreclosure notice" in Georgia) must be posted in the official county organ for four consecutive weeks prior to the First Tuesday sale date, so technically that data is available for free about a month in advance if you're prepared to harvest it from the newspaper.
