You've identified a potential match between a buyer and a property which fits the criteria they are looking for. You'll want to contact the buyer to arrange a viewing for them to visit the property with you and have a look around.
You can schedule a viewing for a property by clicking the Add Viewing button in the key actions menu on the right, or via Property > Sales Process > Viewings.
You can record details of who is going to view the property, the staff member who will meet them and the time and date, recording additional comments if required.
This viewing appointment will then appear in the relevant staff member's diary, as well as the general viewing diary, depending on filters applied.
