Interesting looks like the guy who's still living there did some work around the headers! I guess he felt bad after what the inspector said. Notice the tiles different color. Maybe i can assume it is fixed.
I was there today and the contractor did not seem to think the problems were such a big deal as the inspector suggested...
He said for the crocked floor in the attic and the kitchen he would just put a new flooring over it to make it flat. I guess i do not need to pay him to do that.
He said if they push things up they may crack in with old houses it is better to just leave it as long as the foundation are solid.
Does that sound right to you?
I guess it is a matter of ply wood pieces laid down and some filler to level it off? Or is it a bad idea to let think continue sinking. Here's the spot, i think it is big area actually that needs to be filled. What do i fill it with?

So where the new tiles are he just change that area was weak, as the inspector said was not supported properly, so the up stairs floor sagged?
