Here are a few ideas of things you can do. You go the the local police department and ask for crime reports for the neighborhood. You can also drive the neighborhood and different times of day, and on different days of the week to see what type of activity you see, what kinds of vehicles are there, etc.. You can also look at the school rankings to see where they place in relation to others. Ask you Realtor to show you some comparable house prices from a year ago, 2 years ago, 3 years ago, etc. and compare them to other neighborhoods in the town.
I hope this helps
