Is it advisable for guest to be allowed to come to the listing before they pay or book reservation. Sometimes I get request from guest who wants to come and physically view my listings.
speaking from personal experience, I have allowed guests who live local to view the listing, especially seeing that I had no reviews yet (I do however have reviews now). I would probably ask for the same thing, seeing that a no-review-listing is a bit of a gamble, so I agreed to accomodate the viewing, which also gave me the opportunity to briefly meet the guest who was booking on behalf of her parents and who was lovely.
There's a similar post in the "general hosting" section - about how to more easily communicate when there is a request for a tour, pre-rental -since you don't have a phone or email address yet
