I live in Cincinnati, not sure that matters though just FYI. 

(Side note I do live in a small town so may have to look in the larger city of Columbus which is an hour away, I've even thought of buying a home and offering it to a full time employee to move to this area but not sure if that would just create more headaches in the long run)

To my understanding FHA loan requires you to live there for about a year.
