It's difficult for real estate professionals to comment specifically about the safety or crime rate for neighborhoods because the comments might be construed as either making promises or guarantees about safety, or as improperly steering buyers towards or away from neighborhoods perceived as being mostly populated with one racial or national origin group, which is illegal.
Our recommendation is to be in touch with the local police department or county sheriffs department. They will have access to the most current and up to date information and are generally willing to be helpful.
Feel free to shoot me an email and I'll share what I know about a specific location.
If you could use a referral for a really great agent in your area, please contact me through the trulia form.
You can go to Sperling's Best Places & post your question there. It's a website that provides general information about an area & provides a forum for locals to comment on specific cities.
I will go with the advise of local Realtors from San Jose about specific condition / situation in the area you are interested in!
That's what you should do always!
