I believe Letitia is describing Auction.com because the normal trustee auction you are not assigned a number. You bring cashiers checks with you (not money orders) and a government issued ID with you and that's all you need. I attend the auctions nearly everyday, and yes, sometimes the homes get bid up past your number, especially Auction.com because they market and attract people who have less auction experience but it's a numbers game. You can definitely make money out there I've been doing it for years.
There are several ways to get information on the homes listed for auction because it is all public information. Newspaper, county recorders office, the auctioneer posts notices on the courthouse (although sometimes people tear them down), directly from the trustee websites and 800 numbers, and there are online services (most common method) that compile all that information for you and more but it is subscription based. Hope this helps Michael and feel free to reach out if you have anymore questions.
