Starting my research for Nashville Investment

[Poonam Hemrajani]

I am from CA and looking to invest in Nashville, budget is 300-400, what cities/zipcodes should I look for and why, I am mainly looking to balance my mortgage and get appreciation.  

Based on internet and few post on biggerpockets,  the cities which have been repeatedly mentioned are 

Old Hickory

Mt. Juliet

Hermitage

La Vergne

Smyrna

Murfreesbro

Should I add any more cities in my list. I am yet to see the quality of the property I would get in above cities in my budget
