Lack of tourism = less jobs = population regression. 

The city likes the tourism we bring in.

I was planning on building systems around dealing with clients, then hire an employee to handle them once we start to scale, but for now was going to self manage.Any idea on how could research the amount of tourism that my market generates? 

In a true vacation rental market where the economy relies on tourism, you wouldn't need to.

I’d like to purchase significantly cheaper, but I need to find ways to keep the units rented, preferably short-term vacation rental to maximize income.One strategy I considered was short-term vacation rental during the 10 summer weeks when it is busy and then seasonal rentals during the remainder of the year when tourism is much lower, but still, using this model doesn’t produce enough income (this includes renting the main house as well as the other 4 efficiency units) to support the investment resulting in a very low ROI. 

What impact will this have on areas of HIGH tourism, where vacation renters ARE the lifeblood of the economy?

This is definitely not good for passive investors.I wanted to escape the markets with cheap money and cut-throat competition and I decided to do short-term rentals in locations where tourism is booming to get high rental income and where there is a path of progress for high capital gains.

I don't know the Clarenville area but I have heard that Trinity prices are up due to the demand for short term rentals and tourism. 

What would make them less profitable is if the tourism decreased, but a quick look at the Smoky Mntn.
