that is a massive red flag to me. Sounds like a scammer. Communicating with guests off platform before a booking is made could get you kicked off Airbnb and, even if it doesn't, there are all sorts of other things that could go wrong. I would simply not go there. At best, this is someone just trying to avoid paying the Airbnb service fees. At worst, it's someone who wants to check out your property to burglarise it or for some sort of financial scam.
Unfortunately, Airbnb doesn't give any options to do a video tour prior to booking without communicating off platform. A lot of hosts have asked for the functionality to upload videos to their listings, but Airbnb hasn't made it possible so far, for some reason.
