“Money goes where money is treated best.”Your future ability to attain and maintain financial freedom depends on the city where you invest.Investment TeamAn essential location selection criterion is an experienced local investment team.

I was able to join the local Facebook pages for investors that are local to my area. 

Quote from @Kyle Carter: The comps that come from local real estate agents will be the best for this one.

It would be local for you.  

You can also search for local FB groups that specialize in longer term stays.

You probably have good relationships locally so I would first think maybe upgrading to more units (if you like landlording and management) by selling the duds and then consider what you want to get into.

If you're not having any luck with mortgage brokers (I'd search out the ones who specialize in investments), then go to your local REI meeting. 

It’s a great way to meet local demand while creating steady cash flow.

I saw an example recently in Bloomberg about how local regulations can really shape a landlord’s experience, from what I’ve heard.

That said, be sure to check your local jurisdiction for other regulations.
