PS when you go into the health department ( or whoever controls on site sewage) you may find out also that your individual systems and tanks are fine.. but you want to know for sure before you spend any money.

@Steve Cribb you need to send them a 14 day notice to cure.

Plumbing pressure test with water off (I would also throw in camera test that adds $200 on it's own- I got burnt with a sewage line replacement for $7-8k after purchase). 5.

It's really aggravating because they did NOTHING when the former owner let the garbage pile up in the park, had leaking sewage in the park or the water was turned off for 4 months. 

Sewage lines in Texas used cast iron pipes before 1970s and they are rusting out.....hence I don't buy older than 1980 homes.  

(assuming Seller will not cure).

My wife handed him a 10 day fix with cure notice.

1) have a building inspector come out and see if your shower answer is legal, proper, and common. 2) if so, and there’s no other reasonable cure lower their rent for the inconvenience, offer to let them out of the lease?

I sent a copy of it to the senior lien trustee and requested reinstatement to cure the default.

If you discover that she violates that prohibition, of course, a notice to cure should be delivered right away.
