How to know if a neighborhood is a desirable rental market?

[Jessica Pearl]

Borrowing from a post by @Yadira Gutierrez since we are in a similar situation. 

I have identified a couple of properties in my target town/city. But there are very few rental comps and I don't know if that is because it is not a neighborhood that renters typically look at (i.e. mostly owner occupied), or because rentals go fast. Is there any way to know if a neighborhood is easy to rent out or is that something that can only come from local knowledge? As Yadira had said previously, don't want to end up with a pretty rental property in a sub division that is not sought after by renters.
