Hi there, I have your exact question and am also brand new. I haven't listed my second home (ake-front condo in Collingwood/Blue Mountain area) as it also rents seasonally several months in advance. We require a 50% deposit at time of booking - remainder due 60 - 90 days in advance, non-refunable. This is the customary way of booking private vacation homes in our area too. Also for monthly rentals. For this reason, I haven't listed but would love to if there is a way of doing this - maybe a separate agreement?
Looking forward to learning about this. Thanks for asking the question.
