Abstract: Certain implementations may include systems and methods for determining occupancy. According to an example implementation, a method is provided. The method includes receiving identifying information related to occupancy of a target property by a subject. The identifying information may include a name of the subject and an address of the target property. In certain embodiments, the identifying information may include an actual or approximate investigation date to allow a historical evaluation of occupancy at a specific time in the past. The method includes querying one or more public or private databases with the identifying information and receiving, in response to the querying, subject and property information. The method includes determining one or more indicators of occupancy of the target property. The method includes determining, with the one or more computer processors, a score based on the one or more indicators of occupancy; and outputting an indication of the score.
