I would do as CJ and the other agents have pointed out, if you are not ready to talk to the neighboors, check the web sites first off then drive the neighborhoods at different times of the day, then if it still looks good, talk to the neighbors.
Feel free to contact me with any questions.
One thing I would suggest is simply talking to the neighbors to get their experience. Not only does it help you to find out who lives near you (renters, long-timers, rock bands....etc) but many times neighbors will give a great history of issues that do or do not get reported to the police. I offer my clients a list of questions to get them started on door knocking. It is one of the best ways to get a feel for your new potential neighborhood.
you may be considering. Good Luck.
My suggestion is a visit to the local police station and talk with them.
There are web based statistical sites, but the cops are the best!
