When it comes to any safety/crime related issues, it's always best to contact the local authorities with all your questions, hear all there is to hear firsthand. If unfamiliar with the area(s) do revisit more than once and at different times of day, possibly chat with locals/neighbors. Real estate professionals are prohibited from steering, enticing a buyer to purchase/rent, or not, in specific neighborhoods.
The best way to get that information is to visit the chartlotte mecklenburg police department website and put in the address. It will be able to give you a crime mapping and the type of crimes in that area.
