It may depend on what the previous owner knew about damage & when. Even when good repairs have been effected, the fact that repairs were needed should have been disclosed. It is possible that the prior owners were not the owners when the damage occured & were unaware. Failure to disclose material damage is a violation in GA. but what recourse you may have really depends on what trouble you may be having from that previous damage now. This is a question for your attorney now.
