@Sarah6882 This is a SCAM that is directed to new hosts.
IMO, as a new host, do not accept rentals of more than 14 days to avoid potential guests from turning into tenants (know your local tenancy laws). Turn off Instant Book until you have experienced a few months worth of guests; that way you can communicate with potential guests and vet them prior to accepting the booking. Do not accept guests who have just joined AirBnB and have no reviews. When you have a listing that accommodates more than 4 guests, bookings with 1 guest are suspect.
Best wishes with your endeavors.
