Good to go then, if you have previous auction experience.
You may wish to contact the auction company to ask about the down payment due that day, after the gavel falls. Here, they usually want 10-15% and then they will tell you about the final settlement date (here, usually 30-40 days after).
Also, the seller/buyer usually split the property taxes based on the final closing date. You will want to confirm that also.
And you already know...to determine your TOP PRICE ...and do NOT EXCEED it!
Auction frenzy/bidding (and testosterone) can make one get silly.
