A date and time for a move out inspection can be arranged when notice of vacating is given. (See Moving Out Letter) You and the landlord can walk through the apartment and inspect it together, using the apartment inventory you filled out when you moved in.
If you cannot get a check from the landlord for your deposit at the end of this meeting, be prepared to personally hand deliver or mail a letter requesting the refund of your deposit. (See Deposit Demand Letter)
If the landlord fails to show up for the inspection, you should make a record of the condition of the apartment by taking photographs or a videotape or notes on cleaning and damage. Have the people who help clean write a short description of the condition of the apartment.
