You asked a pretty good question and one thats really hard to answer. We live in 75069 and love it, the zip code includes the historical district of McKinney, the historical downtown square and parts of Fairview. Many folks that don't know, work or live in the area will not understand the charm and character it offers. It is a great place to live and to answer your question I feel very safe.
I think the other agents that mentioned to check with the local police crime stats were spot on. That will give you actual numbers and types of crimes. I would also suggest driving the area your interested in, stop and chat with people and try to get a feel the community.
Best of luck in your home shopping.
