The only tenant I had to work with was ironically the one with the highest income out of all my tenants.

Ironically, this property was also for sale for $16,000. 

Literally just setting any iron based item on your floor that is wet can cause rust stains.

Ironically, this is one of my better properties, literally have not seen a bug!!

Ironically, she was the problem LOL.  

Ironically, the only time I had to kick out fighting couples - it was the ones the tenant had snuck in, rather than asked permission for.But, this is also why I only ever did MTM agreements, too.  

Ironically in Texas and areas in the midwest.I do not see a lot of good deals in the Atlanta market at all.

I left the cast iron pipe exposed and just painted it the same color as the wall.

I am slightly concerned about the age of the house and what lies under all the sheet rock (possibly cast iron plumbing, old electrical, etc...) and don't want to be held responsible for someones child dying due to my neglect of DD and the house burning down.

The drain cleaner snakes or jets the line and rarely are they able to see the items flowing past.Also in some cases it's a combination, it could be an old cast iron pipe with a rough inside surface full of rust, which started to act like velcro to things that flows past, or a slight settlement causing a belly, which again impedes the flow, then the tenant pours down grease, pasta and bean, well, you get the idea.Most of the time you end up eating the cost especially if the plumber can't tell you anything.Now, you mentioned that the clog caused water to back up to a vacant unit next door.
