FIRST, when you arrive, make sure and register if you plan on bidding. You will need a form of identification to register. No money is required to register to bid.
SECOND, arrive early enough so that you can walk the property and seek out the auctioneer or real estate agent to ask any last minute questions. Several open house dates are scheduled so that you can inspect the property and ask questions. It is highly encouraged that , if you are truly interested in a property, you make arrangements with the auction company to bring your own inspector to the home to do a formal inspection prior to the auction.
THIRD, be prepared to bid when the auctioneer begins the auction. He is there to sell and the bidders are there to try and buy. Don't be shy, we're not here to fool anyone. Hold your bid card up high to insure the auctioneer can see your card. It should be clear to all that you have placed a bid with the auctioneer and he saw and received your bid. Shout out if you have to, if you think the auctioneer did not see your bid attempt.
FOURTH, once the bidding has reached the highest bid and no one else will bid higher, the auctioneer will declare the property sold. At this point, you are legally the under contract to purchase the property, by law. The auction company will have some forms and contracts for you to sign and you will need to make a deposit on the property, per the contract.
THEN, all the documentation will be turned over to the title company, who will handle the remaining actions needed to transfer ownership of the property to the winning bidder.
