@Brett Allen Crisp I walked the same path! I was stationed at Eglin in the early 90's left for Sheppard AFB (Wichita Falls) bought a house in the area (still have it and the equity launched my second in in the area).
I moved back in 1998 and lived in Crestview for 3 years we left in 2001 (with a stop in Panama City and Warner Robins GA) I moved back to California in 2005.
I am going back to the area, however, to get a feel for the vacation rentals available. I would like to purchase one as an investment, and vacation home for my family.
Right now Destin is what I am looking at, although I am also open to other areas.
As far as righting your ship, have you tried refinancing your loan? That may lower your payment, if not maybe cash out some equity to use on your next deal.
As you are in Texas it seems like most here (including myself) are keen in investing in that market. I would talk to some other BP members in your area!
The advantage is you can drive neighborhoods, and get a feel of the area that most of us cant do unless we fly there! See what you can find in your own back yard! I am sure you will find something!
Good luck and hope to hear more from you!
P.S Since you are also eligible for a VA loan, look into that to help you! You should be able to buy up to a 4 plex and live in one!
