As Real Estate licensees me and other professionals are legally bound not to cloud your own view of neighborhoods based on their character. I would be happy to discuss stats relating to real estate for the various neighborhoods, if you contact me.
The Zuhls provided a great resource below where you can educate yourself on the crime stats and other things. That's a great place to start. Also, you can simply take a car ride to the various areas you are contemplating to get a feel for yourself.
I can tell you though that virtually all parts of JC rent with relative ease, it is just that they are at different price levels. The key is comparing the cash-flow, not the rent level.
