Abstract: The data processing system includes a property inspection data entry device for collecting and storing inspection data during the inspection of a property. The property inspection data entry device typically includes a scanner which is responsive to labels which are associated with the property as well as various items located about the property which include indicia representative of predetermined characteristics of the rental unit. The property inspection data entry device also includes a data entry device, such as a keypad, for providing manual entry of additional inspection data. The data processing system can also include a maintenance data entry device for collecting and storing maintenance data relating to maintenance activities performed on a property. The data processing system also includes a host computer for electrically communicating with the property inspection data entry device and the maintenance data entry device prior to and subsequent to inspection and maintenance activities, respectively.
