There's nothing worse then having a plumbing leak and having to rip out all the tile you just put in. 

You're going to need to show negligence, so make you you have documentation of prior times it has leaked. 

I'm new to foreclosure auctions.  There's a property in the neighborhood I grew up in that I'm going to bid on. 
Read through the court documents online and it doesn't appear that the owner on title attended any hear...

Even though we were nor in tourist place, house seems almost more than 50% occupancy rate except winter. ( In winter we had mid term tenants)  However, even though our property is popular, because we pay a lot in mortgage, many times it is negative cash flow and pool seems constantly leaking.

Trash, miscellaneous such as water charge for a water leak, umbrella policy or other asset protection, book keeper/tax person, etc.  

Plumbing- corroded cast iron drain lines, corroded copper piping that leaks, sink trap leaks, sink popup ups that are non-functional.

The next morning he returned and found nothing wrong with the unit after tracing the lines for a freon leak. 

This is not only to make sure that people are taking care of the property, but this is also to make sure that tenants aren't overlooking issues that could be addressed now that cost way more later.These can be minor roof leaks, gutter leaks, mostly to do with water penetration.

Lastly, is it possible to put a “seal” on a current shingled roof, should there be any leaks?

He also suggested I bring out someone else to camera the system again to get a second neutral opinion.I hired Cable, Pipe, & Leak Detection and the technician that came out today was very impressed with the on-site system.
