I have seen several management companies in this area try to be "cheap" and they fail. 

The main reason businesses fail is because they run out of cash hence having a strong cash position as a business owner is vital. 

It depends on the terms and conditions of your application (hopefully you presented a formal offer to lease that provided for forfeiture of deposit if the tenant failed to take possession).

and these may be dumb questions but I don't mind looking stupid while I'm learning, I always fail up!! 

Sometimes parts fail and they get replaced and life goes on.

The tenant fails to pay their last month's rent and leaves the place needing new flooring and paint.

@Nathan Gesner like I said I already told him I would evict him if he fails to pay.

They fail more than non GFIs and when one triggers I want to identify it as easy as possible without needing to check additional GFIs (ones that are unnecessary if the circuits were mapped).If you only wanted the portable dish washer and were fine with existing outlets, you could swap outlet dishwasher was plugged into with a GFI in less than 30 minutes. 

Where many investors are failing is wearing blinders to feedback and only wanting what they consider to be constructive feedback that supports their point.

We failed to make sure that part was in writing.
