Crime looks a lot worse on the national averages than it actually is. Some darn thieves around here, but that tends to be related to drugs. I would also add however that if you are concerned about crime, TN has very good concealed carry laws.
Property is still very reasonable. You can get a crappy commute if you are not carful thought. I would advise you to drive your route to work before you buy.
+1 on the Motorcycle heaven though. It is nice to have the park, the dragon and the Skyway all so close.
