So I have a land contract in place (being cancelled due to terms violation) on a low-end cape cod. No big deal other than tenants like to not pay. It was a rental prior to the land contract. 

When it was a rental, the tenants had a history of flushing hygiene products and clogging the sewer. I had it thoroughly snaked by a pro who found multiple clogs and removed them. No problems in 3+ years since. 

Well evidently there was a backup. So instead of perhaps calling a plumber, land contract husband, who is a GC, decided he would tend to it. Now this might now have been an issue, except he went on vacation for 3 weeks leaving his dogs inside. So the neighbor called animal control. I gave permission to enter. Aside from the filth (they usually were organized but always had a stray soda can or Hi-C container laying around from the kids) they evidently fell off the wagon since last fall when I was last inside. Roaches and filth everywhere. But the kicker, husband decided to dig up the sewer?!?! 

So code enforcement was called (and me). So now the house is not inhabitable because there is no sewer. Lovely!
