No, they really didn't know what they were doing.  They focused on how cheap the property was, and they thought they could fix it up and make money, but then found out it was in such bad shape it could not be insured, so they put some money into it and sold it to the squatter.  This was in 2021 and the only time they did it.  They haven't filed taxes in three years, so I am preparing all three years now.
