Newbie in Nashville - Long Term Rental CoC Benchmark?

[Crystal H.]

We are looking to invest in Nashville or the surrounding area rental properties (long term rentals) The objective is to hold and create cash flow.  We can either pay cash 100% for the rental or finance it, looking to keep purchase price under $300k. 

What range of CoC return do those of you doing Long Term Rentals in Nashville typically see? Any areas of town I should be gravitating toward? Tips? :)
