Until you diagnose the problem, you won't know if it is malfunctioning because of damage the tenant caused or if it is defective or worn out. 

No pet damage ever (human damage yes).I make a good bit of extra money from pet fees.

If you hired someone to drain the water and fix the damage that part could be expensed.

Not only will this likely cause thousands of dollars in damages, imagine the size of your water bill if it's running full force for a week or two and no one notices...$$$$. 

I believe that there may be some damage although I am not sure to what extent.

The posts that really get me are where someone has bought an out of state turnkey and not even in a year in they have had an eviction that took a couple of months and damage to the unit and then a few more months of trying to get a new tenant in, who is probably just another warm body. 

Damage?  

Key features are insurance against damage or loss to the house itself and attached/related structures (garage, covered patio, etc) and some degree of liability (I like to get $300k).

Our cleaning team takes care of laundering the linens; we handle replacing any missing/damaged linens.

So, we hired him for framing for damage part of the house - interior and exterior, paint, tiles, kitchen cabinets, exhaust fans, baseboards and tiny cosmetic things.
