Here’s how it works: Just fire up Homesnap on your iPhone or iPad, pull up the home’s listing, scroll to the map, and tap “Walk the Property Lines.” As you walk the perimeter of the home, your iPhone (or iPad) will display the property lines on top of a real-time view captured by the device’s built-in camera.
