A computing system contains a processor that is configured to receive, with the user interface, a registered access code and access permissions from a remote user of a property having a property location. The registered access code may be configured to provide access to the property. The access permissions may include a predefined access period that the access code is valid to provide access to the property. The processor may further be configured to receive a provided access code of a local user of the property in response to a user location of the local user being near the property location, match the provided access code with the registered access code, and grant or deny access to the property based in part on the provided access code matching the registered access code and being received within the predefined access period.
