It appears that you need to register for more details. So follow the link back and fill out the registration information as prompted. If that doesn't help try to find out which auctioneer or auction company that will be hosting the auction and call and ask them.
You'll want to ask them how much they need down that day, what the time limit is to produce the remaining funds, what kind of deed will be provided to the buyer, and maybe ask if you can walk through, or even have the property inspected prior to purchase.
