"Finding the next Clarksville"

[Lon Sierra]

New investor. Have 2 doors (Milwaukee and Clarksville). Clarksville is hot and I'm wondering how best to find the next place that was Clarksville say 2 years ago...where I can get in while it's still a relatively untapped market. I've been looking at growth rates, etc of towns but am wondering if there's a trick to discovering that next hot market (besides foreseeing the future). Any tried and true methods? Good websites to visit? Other search criteria I'm missing? Market recommendations? Kindly talk to me like I'm a 3rd grader cuz that's about how I feel at this point in our REI career. ;) Many thanks!! Jill Sierra (wife to Lon)
