rental security
When a complex tries to pull a fast one in not having to return you deposit, i.e. saying that they had to redo the carpets after 1 year when there was absolutely nothing wrong with them, ergo, forgoing you deposit refund and actually asking you for money.
Re: rental security
You can sue for your deposit. You might show up at your old address one day and knock on the door. See if the carpet is new.
