The foreclosure process is long and drawn out with many steps along the way. The first step is usually a short sale. This means that a homeowner has decided to sell their home but owes more than the home is worth in the current market. So they work a deal out with their bank to sell it for less than what they owe. If the seller is successful in selling it, the bank may forgive the rest. If the homeowner in unsuccessful in selling their home it is foreclosed on. It then goes to sherriffs auction where it goes to the highest bidder. In some cases the bank will actually get the home back and put it back on the market at a very discounted price. This entire process could take more than a year or two depending on the situation. So "Pre Foreclosure/Sheriff Auction" means it is in the process of going to auction. Hope this helps.
