McKinney, Texas - A good area for first rental property?

[Max A.]

We recently moved to North Dallas area and are looking to buy our first house, which I later want to convert to a rental property. Initially, I was looking at Frisco and Plano areas but not able to find any property in my budget (~250K) that satisfies the 1% rent rule. 

From what I gather McKinney, Prosper and Allen are up and coming places. Would these areas, specifically McKinney a good area to start our first investment property? Thanks for your inputs.
