@Shelley319 When a listing is under new ownership, neither the present owner or you can just keep all the reservations- guests booked presumably after reading reviews and it would be unethical not to apprise them of the situation and give them a choice whether to keep the reservation or have it cancelled. They have no past reviews to go on with a new owner, who may or may not be a responsible host. Guests aren't like furnishings which can just be passed on.
As for honoring the cleaning fee that booked guests paid "in good faith", it isn't a matter of being nice- you can't change fees, cancellation policies or anything else on a confirmed reservation- whatever was in place when the guest booked must be honored.
I guess you'll have to talk to the present owner as to how to handle the booked reservations, but as I said, guests need to be informed and given a choice.
I'm not sure if Airbnb will assist in changing over reservations to your new listing for the guests who want to keep the booking so they don't have to rebook and pay a service fee again.
And the present owner should not be accepting more bookings at this point.
I don't quite understand why you think the cleaning fee should go up just because you won't be living nearby- presumably it would take the same amount of time to clean after the place is yours as it does now. But if course you can set any new fees you want.
I should think that if anything goes up, it would be the nightly booking cost, as you will have the expense of hiring a local co-host to manage things.
