If buyers want to take a tour of your home from the comfort of their own couch at 10:30 pm… let them. It’s easier for them, and it’s easier for you.
If that tour helps them realize there is no way they can make the bedroom situation work for their needs, you won’t be put out for a showing appointment.
But if they do schedule a showing after seeing the tour, it’s likely that they are very interested in buying your home.
