I always suggest you talk to the CRO or community resource officer at the police department.
The problem here is everyone has a different idea of safe. In a discussion I had yesterday with a friend was that I recently went in a house in what I consider the hood and they had no security and the windows were open to let in fresh air and no one was home? They weren't that worried I guess?
I also remember one time I lived in Dallas and when talking to the police after my house got robbed. I told them I think I live in a good safe neighborhood and their response was well of course, that's where the bad guys come to get their good stuff...makes sense.
I also recommend driving through the area in both daylight and at night time. Knock on a few neighbors doors and ask for opinions. See if there is a neighborhood crime watch group.
