Investment property north of I-380

[Rahul Kadakia]

Hello everyone,

I am an out of state investor and so far I have bought 2 investment properties in Frisco (~$350K range). My plan is to buy and hold for the long term (10+ years). I am now thinking that I should buy lower priced properties in the outer areas because I am assuming that those properties will appreciate faster than something more central - Frisco/Plano/Mckinney.
Is that assumption right? Do cheaper properties ($275K range) in the outer areas appreciate more than more central areas?

I am looking for areas that are expected to grow in the mid to long term - ideally have a major employer, have upcoming infrastructure projects (e.g., a new rail line or major park), etc. How can I find out more about upcoming infrastructure projects in North Dallas

Which of the following towns would you recommend I buy my next property - do let me know your rationale: 
Anna, Van Alstyne, Howe, Sherman, Denison, Gunter, Pilot Point, Tioga, Collinsville, Whitesboro, Sanger, Valley View, Gainsville.
Also, would you prefer Wylie, Lavon instead of towns north of I-380?

Thank you very much for your help
