Thanks for the additional clarification.
It sounds like the guy is angry that his attempt at tax fraud didn't work.
I will say that your agent was rather foolish to agree to have you sign the contract with that clause in it. You certainty didn't disclose it---they did----but I don’t see where they have a problem either as they were not bound by your contract. They didn't agree not to disclose.
The MLS requires them to disclose the sale price as well as other steps in the sale process. The county requires the disclosure of the sales price for taxation purposes.
While he can file a complaint if he wants, it won't get him anywhere. At most he was thwarted in his attempt to defraud the county tax collector. Other than that, there are no damages that he has suffered.
The state real estate
board is aware of the disclosure requirement of sales prices so I don’t see this as anything more than a buyer having a tantrum.
