As defined by Auction.com there are 7 steps to the Residential Auction Process, which you can access here: http://www.auction.com/auction-process/residential.php
However, to be fully informed of your options please review this blog post that covers the 4 ways you can purchase distressed property:

Note that typically you must bring a cashiers check for the down payment to be admitted to the live auction. Also note that some properties do not allow financing.
When buying through an auction like this, there is no inspection contingency. Make sure you inspect the property before bidding. It would be much harder to cancel and get your deposit back after winning the bid and signing on the dotted line.
I would suggest setting a limit for your self before entering the auction venue, you might get carried away. Also the bids are before the 5% premium.
