Take pics of any existing damage to a rental as soon as you move in and email it to the landlord/leasing office. I did this after a landlord told us he took the last tenant's entire security deposit for damage (to be fair, it sounded like the tenant really messed shit up). I took that as a flag, and sent him a very detailed email of every hint of damage I could find. 12 months later, after we moved out he emailed me to say he was going to deduct $100 from our security for damage. I reminded him of the email I sent him, and never heard from the f*cker again.
