Terry it is you as the host who has accumulated the reviews and the bookings......not the purchaser.
Past performance is not transferable on Airbnb. Those guests booked with you, not a new property purchaser. The sale of a property nullifies any past hosting attributes.
The new purchaser has to open an Airbnb account, explain the situation and give your prospective guests the opportunity to either take a risk with an unknown new host, or cancel their booking.
