I am new to the site and I am currently exploring options for non traditional financing.

Didn’t go the traditional yellow postcard route or picture of a house.

In fact, based on the fact you don't have traditional W2 income, I think you should be looking for a commercial loan (from a portfolio lender).  

My current financing plan is to use traditional financing since 20% down isn't an issue and both of us have good (700+) credit.

We can't buy with a traditional loan for another 7 months because my boyfriend's job switched from 1099 to W2 the year before last.

A lot of traditional analytical templates, p&l sheets I found online don't really factor in some of the unique nuances of short term rentals like this.  

This has the potential of being a 12 month rental, but not in a traditional vacation rent way. i have been told that a lot of the local and seasonal vacation employees  need places in the off season.  

If you are looking to buy a rental, you'd want a more traditional type mortgage.

Sevierville cabins are more traditionally "out of the way" and quieter (at present).

But if it is a traditional IRA, both gains and contributions will be taxable and early withdrawal penalty will apply when you take it out before you reach 59 1/2 years old.
