Because of its location there are a lot of short term rentals which results in fewer options for long term rentals and higher rents if you can find one. 

This is the best evidence you can have, especially if a guest calls the OTA and gets them involved. 

And are there non commercial options available? 

Options include real estate syndications (group investments), funds, or real estate crowdfunding.

Are you interested in long-term financing options?

Your PM should be handling this, you should not be involved Good Luck  

Another option is DSCI loans this just uses property rents to qualify not your personal DTI.

I am currently using Zillow to screen tenants and had the application option turned on so I have candidates who paid $35.00 for the Zillow application fee.

Anyone who is actively involved in health care has a competitive advantage in doing mid-term rentals because you have access at the hospital to help find travel nurses suitable temp housing (yours) while they are in town.

Your only option is do the work yourself or hire a GC.
