If you just want to know what the most recent sale price was for a property, you can just look it up in the public records. If you have a real estate agent friend, your friend can also easily access that information as most real estate agents have online access to this kind of info. I hope this helps.
I was curious about that too. Even attending the auction, it was tough to keep track of because the winner bidder would go over to the closing table, and often the home would be back up for auction later in the day or still listed as available, several days later. I haven't found a formal or complete list of the final prices, however, if you can wait until the transaction is closed (about 30 days) I can look up the sale amount if you have the property address.
