The highest and best use for your single family rental is to rent it as a dwelling, not as a storage facility, dog hotel, meditation chamber, or whatever other oddball deal we can come up with here. 

So far I joined the Dallas REIA and have been involved with The Colony Chamber of Commerce (I work for the chambers president) and have attended the Most recent Texas Legends Networking event.

In terms of sub markets to look at, I'd advise looking city of chambers websites, city websites, commercial office space reports, and business journals.

@Cameron Chambers Everyone above is exactly right!
