Newbie looking for rental prop suggestions

[Atta Bari]

I'm new to real state investment and looking into the rental prop. Information in forums and webinars is very informative but also overwhelming. I'm not exactly sure to where start from. i.e turnkey vs finding & buying prop using conventional ways?

I'm in Dallas, TX and preferably would like to start locally but also open to other locations. 

For me, cash flow and appreciation matters. I'd also like to know if there are any particular zip code within DFW area which are good for rentals and comparatively have less vacancy rate.

Looking forward to hearing suggestions and thoughts which will definitely make a huge difference in my journey of real state.

Thanks in advance,

Bari
