In Georgia there is a process in place where the homeowner can apply for the overage.  However, that is not before the county takes yet again another cut for having it reviewed by an attorney, paying for a title search (as if the one they did prior to the sale is no longer relevant) and other junk fees they tack on.

IF the homeowner doesn't apply for the overage (and most don't because they A. don't know that they can and B. Have no idea how to go about it) then the county is supposed  to file an interpleader which of course is also deducted from the excess funds.

 So technically yes, you can get money back depending on high the tax buyer jacked up the price on the tax sale, however it's not an easy process.

I hate tax sales and the people that they hurt.  Anyone who does work in GA knows that InVesta is the absolute worst.
