Abstract: Systems, devices, methods, and program products for enhancing structure walkthroughs are disclosed. In various embodiments, a method includes establishing whether an interested party is properly granted access to a structure to conduct a walkthrough. If establishing that the interested party is properly granted access to the structure, (i) instructions are transmitted to a gatekeeper device to grant the interested party access to the structure, (ii) the server end determines whether an alert condition occurs during or immediately following the walkthrough utilizing a current location of the IP device, and (iii) a notification is generated on the IP device indicative of the alert condition when detected. The alert condition may be a determination that the interested party remains within the structure following elapse of the walkthrough, or a determination that the interested party is traveling away from the structure without completion of a mandatory check-out process.
