We have a unique property we are looking at in upstate NY.  

It's probably a good thing, but as you can see, the theme here is growth management -- can they keep growing successfully, or will they encounter sheering forces that cause a problem?

There was an interesting post on Realtor.com - https://www.realtor.com/advice/home-improvement/deep-theme-d...It is all about the creation of themed homes and rooms.

But the area has been doing short term for decades due to the theme parks.

Muskoka is a very unique market in it's own.

Remember to factor in the ancillary businesses that any particular theme of business needs, as much may not be directly tied to the base business (e.g., a cafe where patients can digest bad news - not a medical service provider or medical support provider, but ancillary nonetheless. 

Definitely a unique position to be in. 

If it's just speculation, start by reviewing the law to see if there are any unique requirements for a business.

Your record of this deposit (via teller slip or online transfer) will be your receipt of payment.This elimates complextity and the additional steps/rules that come with using a third party to collect rent.I get an email alert when a tenant makes a deposit, and each rent amount is unique so I know who has paid in case they don't have the teller add a memo to the payment.They can transfer funds online, or walk in to a local branch with cash, personal check, wampum, etc. 

Make your furnished unit unique and market it everywhere.
