Congratulations on your assignment to Hurlburt. To stay within 15 miles of the base, you need to be looking at properties in Fort Walton Beach, Shalimar, Mary Esther & Navarre (not in any particular order). All have some nice neighborhoods.
If you are purchasing a home/townhome the only area I would caution you on is areas that may put you in a flood zone. Outside of that, it's actually against the law for a real estate professional to steer you towards or away from any neighborhoods.
If you would like a list of properties that may meet your needs, I would be happy to send to you. Let me know if I can help.
