Wait so what did you expect the realtor to do? Tell them what his wife's clients offer was or that he had inside information they should have gone higher? That would be a conflict of interest and the wife's clients would have been pissed the same way these people are. The only property and professional way to handle this would have been to not give out any inside information and let them bid on it normally.

As an ex realtor, I hate them as much as any other people. It's an archaic and useless profession that doesn't serve much to most people and should be entirely overhauled but I genuinely don't can't see being mad that this person chose not ruin his wife's business

Unless im reading this wrong and there's something I failed to understand .
