I would have (and have done some worse) inspected it. It is easy to write the report for these. Everything is broken, trashed, worn out, did I say broken yet, and needs to be replaced, beyond repair, not salvageable, deteriorated beyond recognition, unsafe, unsavory, polluted, spoiled, severely damaged, etc. etc. etc.
They may have been buying it simply for the land and needed an inspection just to show the sellers the house was not worth zip.doodoo. I have seen some properties where the house was completely worthless but the sellers (and their agent) were trying to get money for something that just needed to be pushed over. All inspections can’t be on nice pretty homes with few discrepancies. I would have charged extra for this particular pos just because of the time to write up the report. LOTs of pics too, just so later none of the participants could try to blow smoke up any open orifice as to the actual conditions at the time of the inspection. In this case a thorough narrative report would be issued so I could describe in minute details the conditions and use every adjective to hammer the point home.
You learn how to write these kinds of reports in hurricane country. I call it a “Sherwin-Williams” report…you don’t just cya, You “Cover the Earth”
