To get the most up to date crime stats for an area i recommend that you visit the Charlotte police department website. They provide you with a lot of information on crime in the area you are looking.
go to http://www.cmpd.org Once there click on the tab on the top right for your safety. Then the crime mapping and put in the address and it will give you the types fo crimes and frequency out as far as you want distance wise and when they were reported.
There are other sites that offer soem information but i have found this one to be the most reliable one and up to date.
