The price was a 100,000 more than they were initially ready to spend. Two hours later the realtor calls back. Another client had topped their offer by 50,000 more and was ready to pay cash down . Every day we get to hear of more outrageous experiences. The price the house listed at is a mere formality.
Listed prices are no longer the price at which a house sells.
They are merely a foundation from which the bidding takes off. Silent bidding, unlike an auction where you can see the counter bids and raise your price accordingly. You make an educated guess about what the house must be worth in today's inflated market and write it down on a sheet of paper. That's your bid. Mostly people put down the maximum they can afford to pay, usually the combined value of all their assets.
