For crime rates in different parts of JAX, checkout http://www.coj.net/departments/sheriffs-office.aspx and for other stats checkout http://www.homefacts.com
Another great resource is the Florida Dept. of Law Enforcement. http://www.fdle.state.fl.us/Content/home.aspx
My company has a property management division and you can contact them for assistance in that area. You can also preview rental listings at http://www.watsonrent.com
Let me know if I can help in any other way.
