Hi @Leana5 🙂 You don't have to give him anything more than the cancellation policy says. And all that is handled automatically when the guest cancels. It doesn't matter what he tells you. If he wants more money tell him that he has to contact Airbnb and that you can't do anything from your side. Airbnb will only side with him if he can document "extenuating circumstances". Always just tell them sorry you can't do a thing from your side as you won't get paid before after check in and that Airbnb handles all the money issues.
Some hosts offer to give the guest a refund IF the dates get rebooked.
Make him believe you really don't have a saying. That is what I have done 🙂
About your question. When your guest books he won't get more money back than the cancellation policy promise him when he books. So I don't think it would make sense to book your strict cancellation home just to have your place "on hold".
Btw if you want to write to someone specific make sure to tag with @Leana5 otherwise the person won't know you wrote as no notification will be sent.
