Which reports do you use for audits?

Quite a few but move ins / move outs and I'd usually check a couple months worth. It's surprising how many managers feel the need to cheat the system and do fake move ins and then not even be clever about it. I think the biggest "OMG WTF" moment I ever found was a manager who had a unit "sold" at auction, the buyer instantly rented the unit, never paid more than about $20 upon the rental then they got "sold" in auction, new buyer did the same exact thing, went to auction again then magically is out of the system with no notes before auction date and rented back to the ORIGINAL tenant. So no real rent paid for about 9 months. All of this came up prompting a in depth look after the tenant had a falling out with the manager and told how she was paying him under the table the entire time.
