I know this from my brother-in-law, who lives in Glasgow and was always outbid last year while looking for a larger apartment. However, he does not complain, as that is the usual procedure there.
Different countries, different customs..
At least here with us, this is not common practice. And I also want to point out that here in DE the bank also assesses the property accordingly and the sales process can be delayed if the creditworthiness or equity of the highest bidder is not sufficient after all.
There are countries where the sales process takes just one day, so the back and forth in negotiations can certainly be done, but here it is well known that it takes significantly longer.
I set my desired price, which was already 50k above the highest valuations of some banks (according to our mortgage broker). The risk would be too great for me that I would not receive the money from the house sale on time for a few thousand more and that maybe other interested parties would subsequently back out.
