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

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.

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

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

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.

If my kitty was fat enough, I'd take 5% any day and throw my laptop and iPhone in the trash, sleep till 10am and play guitar with my amigo's haha

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

@Edward Lui management is free I use my iPhone.

So, now since I am able to afford literally new construction, I am leaving this leaking moldy house.
