I am looking at picking up a property for a rental that i am sure had non-permitted work done - a lot of it...  This is a foreclosure property.  It was a trailer that has been completely bricked over with a roof added and a large bedroom added.   The work looks like good craftsmanship, and the place seems structurally sound.  Can i get thru closing?  Can i get sued by a tenant 'claiming' something later?
