Tenants claim they are being charged for damage that existed at the time they moved in.
Or, they claim that the cleaning and repairs for which they were charged upon moving out were not really needed. You will need proof of the condition of your rental unit at the time that you first moved in, and on the day that you move out and return the keys. Without this proof, you will have a very hard time disputing deductions from your deposit that you may consider unfair. This is not a repair list. If your list is vague or incomplete, you'll pay the price.
