Neighborhood research - Charlotte

Hello,

I was wondering if anyone can give me pointers on how they research the neighborhood when investing in a town they are not familiar with. Is there any website that gives you neighborhoood information? In particular, I am currently researching Charlotte for rental houses. I would like to invest in a while collar neighborhood where the numbers still make sense and I can still get some cashflow positive properties. Ideally, I would like to stick to houses under 150K. Thanks!
