Evaluating Smaller Markets - Ohio

[Peter Baldridge]

I'm wondering if anyone can help me answer this question. 

I'm already invested in long term rentals in a smaller market outside of Cleveland Ohio. I'm interested in mid-term rentals for travel nurses. There's a regional hospital in the area, and I see a few mid term rentals located next to it. However, I've noticed that most of these rentals are completely vacant and show no bookings in the months ahead. Worse, they have no reviews.

My question is: is there simply no demand in this area, or is there something that I'm missing? Secondly, does anyone have a good metric for evaluating mid-term rental demand?

I would appreciate any and all feedback even if it's just telling me that I'm missing the obvious.
