Every home that is a foreclosure was at one point on the courthouse steps for public auction. Call the courthouse to see when they are holding their next auction and go check it out.
Before you consider an auction, you may want to speak to an attorney or title company to understand how title will convey on these properties. In most auctions, you will need 5-20% in certified funds at the auction. If you fail to perform to the terms of the contract, you will lose your down payment. Why are you considering an auction?
