As anyone can tell you, the property market is going absolutely gangbusters right now. So much so that a bidder at an auction in Sydney’s south last Saturday accidently bid against herself just as she was about to be declared the new owner of the property for sale at the hotly-contested auction. The final price was $1.62 million, with her previous bid being $1.619 million. The underbidder’s last offer was $1.618 million.
