Personally I use the Trulia Crime and amenities tabs and also http://www.crimereports.com which gives you a little more information than Trulia in the area of sex offenders, where you do not want to buy in that area if you have young kids or plan to sell in the near future. I have found that the more amenities, the more insidents in the area, even in nicer areas like Roswell, Alpharetta, etc.
In the past, I have called the police department and I have been told that they had no calls to that street, but that is not good enough.
I am not a realtor, so I can speak my mind on these matters, since I am a buyer and have been considering moving to Snellville, GA late this year.
I have been tracking Atlanta, GA real estate since mid 2012 so when my company transfers me, I will be very informed with home values, crime reports, taxes, travel time to work, entertainment, shopping, and most of all, quality of life.
I have done alot of business in snellville and resdie close to that area.
While I feel in my opinion that it is a fine area, may I direct you to the nearest police department
for crime data and reports, as licensed Professionals are not allowed to answer such question.
Let me know if you would like to arrange a showing for this home.
Best with finding your Dream Home!
