Your best bet to find out about a neighborhood is speak to the neighbors, the local police dept. and check the Megan's Law website (I attached the link). I would also suggest driving by the home at different times and days.
As agents, it is against our code of ethics to say if a neighborhood is safe or not. First because safety can be a personal judgement call and, second, it can also be used in 'steering' or 'redlining' (which can cause an agent to lose their license).
