Short Term Rental Question

[Vincent DeCarlo]

Newbie here. I have an opportunity to acquire a mountain home through a subto agreement. It would be a great AirBnb investment but my issue is that I'm having problems running the numbers. What tools or formulas are you guys using to calculate vacancy on short term rentals? Anything else, other than cleaning fees, that I should consider that affect short term rentals on top of what a regular rental requires? I'm trying to put together a budget. Thanks
