When you arrive to an auction site, register for a bidder number and read the rules printed on or displayed on posters, brochures or handouts. Again, ask questions if you don't understand a policy. Inspect the property you're interested in, as most are sold at auction, on an "as is, where is" basis. This means it is not guaranteed, however you may freely do any inspection you want before the auction starts. Typically the property will be open for previews prior to the date of the auction.
In order to bid at an auction, you need to make contact with the auctioneer or the ringperson. A ringperson is someone who takes bids from the audience and then passes those on to the auctioneer. To bid, hold up your bid card, your hand or shout "yes." The auctioneer or ringperson will make eye contact with you, take your bid and immediately turn and seek another bid. You can remove yourself from the process at any time by shaking your head "no" or saying "no" if the auctioneer or ringperson turns your way. Should an auctioneer or ringperson misinterpret any of your signals, simply report the mistake right away.
