I have told my clients for years, that they should go out on Friday and Saturday night to the neighborhood they are thinking about. I've even taken mine out in my own car, when I felt it would be helpful. A good time of the month to go is around the 3rd when government checks come in. You'll be able to tell how people act when they get their check. Some will act "ghetto" some will not.
As an investor, I've had "ghetto" people of every ethnicity, and upstanding citizens of every ethnicity.
Before relocating to where I reside now, I did my homework. I used crime statistic websites, school API score websites, spoke to San Bernadino Sheriffs Officers about properties I was interested in.
Also, without disrespecting the realtors that are on this site, I would avoid asking their opinions about specific neighborhoods without confirming the advice with the previously mentioned resources.
