A viewing is when a few members of the production team take a look at the space before deciding if they would like to move forward with the booking.
Often producers will view multiple homes before making a decision. Producers need to view the space before booking to make sure the photos are indicative of the space, and to better plan for their shoot.
Once you have accepted a viewing request, the producer will receive your address and phone number and a few members of the team will stop by to view the space.
They will not show up unexpected, you will have agreed to a date and time in advance that you are available.
