Move In Checklist
If you take a security/damage deposit, you MUST prepare a move-in checklist detailing the condition of your rental unit. The checklist should be specific and must be signed and dated by both you and the tenant. This is the list you will return to at move-out to see if any damage has been done to the unit other than normal wear-and-tear so it is in your best interest to make sure it is thorough and accurate.
See the state laws on security deposits and checklists and on security deposits and trust accounts.
