There are other good spots too though where you might broaden your search landlocked vacation rental tourist destinations with cheap real estate like Poconos PA, Ozark area of US (Branson, MO; Hot Springs, AR; Broken Bow, OK *Not the actual Lake of the Ozarks area though, too seasonal) If you're prioritizing cash flow, pick tourism hubs with strong track records for occupancy curve that stays full for 9 or 10+ months at the least.

With all that said, I would go with a long term rental - especially since you mentioned it is not a destination location.  

One of my contacts at short-term rental data company AirDNA mentioned to me that Mexico is one of the most sought-after destination by their clients. 

We are by no means a vacation destination, but as many people are saying, anywhere that isn’t the coastal markets is having a large influx of visitors (some becoming permanent).

Idaho has become a popular destination for transplants from California, particularly from San Francisco and Silicon Valley.

And there is a demand for long-term furnished rentals or rentals by the month in destination cities like Scottsdale.

We're in downstate NY and would like to find a property in a warmer climate in the Southeast within a 3 hr flight from us that is typically a destination people drive to.

The home is located in a great spot inside a tourist destination locale.

VERY strong short term rental market between Destin to Panama City Beach. 

How will you know how to get to your destination if you don't know what your destination is?
