Plenty of other possible explanations:
Are there any lawsuits related to the property ? Is it being sold, transferred or refinanced. If his loan has impounds, did the lender fail to pay the taxes ?
He could be making the decision to let it go, or it could be any number of issues.
Time will tell.
Has anyone on this board ever had their lender fail to pay impounded taxes on time ?
It happened to me once in the late 1990’s and they ended up paying the fine for me. Luckily, I am not in the financial media business.
