I would apply to every unit I could stand living in for the next 5 years. Then I would think about transferring to my hometown, in your case, Memphis.
From what I've learned.......Most units want their guys to be "local".
Just don't leave a unit right after they put you through UPT and associated airframe training.....pay them back and then entertain a transfer. Who knows, you may end up enjoying your "new home". good luck.
