@Alison422 No, there is no way to take a deposit before the guests arrive. Airbnb takes care of all billing, and there is no way to take payment in advance.
One thing you can do is set your cancellation policy to strict

This explains all of the cancellation options.
Super Strict 30 and 60 policies are by invitation only.
It is challenging if you have a place with a short window for bookings. I'm in the same position with my cottage: I only have 2 months during the summer to make all my money for the year. Unfortunately, due to Airbnb's cancellation policies, I don't really take bookings through them for critical weeks. I have it listed on the Airbnb site, but most of my bookings come from elsewhere.
