looking for C+ / B zip codes

[Richard Cumberbatch]

Hi all, 

I'm an Canadian Investor looking around the state of Alabama trying to get some input on the best zip codes to focus on. planning on grabbing some properties to BRRR but want to focus on the C+ / B areas.

so far most people are recommending the Huntsville AL area.

feel free to also share some local wholesellers whom have list / pages.

TIA
