I advise all of my clients to knock on the neighbor's doors and tell them you are considering buying the home next door. Ask them what they like and perhaps what they don't like about the neighborhood. You can also look up crime statistics on the San Jose Police Dept. web site, http://www.sjpd.org/CrimeStats/
You may also wish to check school test scores at, http://www.greatschools.org. Good luck.
