From the article: >That said, he warns that a bid too precise may make the bidder look suspicious, or even ridiculous, to the recipient. Bidding $1.03 million for a house is one thing. Bidding $1,033,235.83 is another. >If a bid is too precise, it may strike as strategic to the recipient, rather than being driven by superior information,” Keloharju says. “This may lead the recipient to rethink whether the bid is really informed.” So I think $153k is an ok level of precision. $153,900 is starting to be “too precise”. $150k is definitely too round. It’s all a personal judgement call on how precise one should go but I think it’s easy to see what is too extreme (with cents in it in this case).
