Analyzing an MTR market

[Assaf Lowenstein]

Good morning and happy 2023!. 

How do you analyze a market for potential rent and desirability? 

I'm analyzing an MTR market in Arizona, looking for potential rent and desirability and I'm getting some mixed signals. 
Agent says that a TN told her that "market doesn't have a lot of options so nurses are not applying". I do see very little inventory in FurnishedFinder and prices for a room are ~$500. 

What's a good way to learn more about desirability of location and potential rent beside FF? any other recommended sources?
I was thinking calling the local medical centers and talk to whoever coordinates TN or is doing recruiting. 

Thank you!
