Primary residence turned to Rental Property

Hi BP, 

I am new to the BP community and to real estate investing. I have been researching, reading, and evaluating properties as @Brandon Turner recommends on webinars and podcast.  I currently live in Philadelphia, but I will be relocating soon. As a first step in the investing process I am looking to purchase a single-family home in my new city, with the ultimate goal of turning it into a rental property. Does anyone have any advice on things I should consider or look into as I explore this possibility?
