You can see your ACT score is quite competitive in TN and quite well above the average TN applicants to Vandy in 2016. Remember that Vandy admit more students from its own state than any other region. Students in TN definitely has better chance to get in than out state students in comparable states, if the ACT Profile Report -state is correct, so I think you should try to apply ED1.
