A panorama allows potential buyers to look around the room. It's almost like being there, and it gives a buyer a good idea on how the room feels, flows, works. A very persuasive improvement over a conventional static photo.
Besides showing the flow of a room, the exterior view allows the viewer to look around the neighborhood with a single photo.
You can order individual panorama shots, or a 360 virtual tour. The virtual tour consists of panorama shots for each main room, and they are connected so that a viewer can virtually "walk through" the home and see it as if he/she was viewing the home in person.
This is becoming more useful in this new age of social distancing.
