Your local Recorder's office will have the auction information. If you are new to auction buying, I suggest you get your research lined up and talk to a few folks at the office. They can help you get some information. Also, go to a courthouse auction a few times to get a feel of the flow and ask the people there some questions.
Some may be a bit closed minded because they don't want to teach anyone new, but some may open up. You never know.
