You are providing upscale furnishings, all appliances and often amenities - not common in long terms - and you are stocking it with supplies and staples - virtually unheard of in long term rentals.

If it is furnished you can use furnished finder but that tends to be shorter term. 

If you do end up refi out of it, think about putting the money back into furnishings for using it as a STR.

I decided to rent furnished, left the furnishings in place,  and hoped for the best.Within 3 weeks I had two tenant applications.  

We're just over a year into the short-term rental game and have primarily relied on Airbnb and Furnished Finder.

Furnishing and finishing the details took 3x longer than I thought, however, I am very satisfied that I received a mid term rental inquiry for traveling nurse and subsequent booking within 1 week of posting!

So we have changed the rental strategy for the first few years to a furnished model to help the cash flow until we can rent to a long term renter in the future. 

My thought is to add a furnished second story and either target the travel nurse audience or AirBnb.

Investors often overlook attention to detail on furnishings and amenities - to their peril.
