Hi @Joni114 - you purchased a property, not an Airbnb. The host had these reservations, not you (nor the property). You cannot 'import' these bookings into your account nor will you get the cash for said bookings, unless that is the host who you've purchased the property from has made some sort of promise to hand it over. Tread very carefully in these circumstances.
Not sure what you mean ref 1/2 day availability - care to expand?
