If you purchased a foreclosure property at auction, and the FHA apraiser did not reference any structural problems with the property before the successful bid, you unfortunately have no recourse.Whenever someone buys property at a foreclosure sale, they take the risk that there are problems with the property that no one has to disclose before the auction. As to the appraiser, the appraiser solely appraises the property and has no training, experience, knowledge or duty to find any structural or other problems with the home you bought at auction.
