Inspected a 50 year old home the other day that had numerous items hidden by the home owner, the reason he hid them was because of a failed sale from a previous home inspector. Come to find out none of the doors would close due to some signifigant settlement or foundation failure. He then took it upon himself to cut the doors at an angle to fit the jambs, I only caught it because the tops of the doors looked a little jagged. I then put my torpedo level on them and noted headers were out of level by 3/8" in some areas…
Recommndation: Several door jambs out of square, this condition indicates movement and warrants further evaluation by a licesned structural engineer.
