Rental property owners should be careful when hiring a property manager. The manager is the person who has interaction with all tenants and is given access to the master keys. Landlords should always check a manager’s background to the fullest extent allowed by the law and closely supervise the manager’s job performance. If tenants complain about illegal acts by a manager, landlords should take complaints seriously. The owners should also be aware to make sure that their insurance covers any illegal acts that may be caused by their employees.
