Tenant ended up taking everything out and the deposit was not enough to cover the regular damage plus the items that were basically stolen. 

We had to file paper copies this year because my wife's SSN was stolen last year and used to file a fraudulent tax return.

I tell people to fill out the application (free) but only pay for the background/credit check if they are seriously interested....it's non-refundable and I don't see a dime of that $$....its not a profit center for me and I don't have to go through the hassle of entering all the info.....and I never directly see their SSN etc....I have no hard records of their personal info, so I can't have any of that info stolen or used by me

If you lose it or it gets stolen, what do you do?
