I live 15 minutes outside of Jacksonville so maybe I can help.
First off there is a state income tax so think you are a bit off there subfixer. Also alot of hidden taxes like wheel taxes and such.
The area is nice in a lot of ways, especially for a military town. I have lived all over the world and JV is nice for a military town, there isn't a place here I would feel uneasy about walking around even at night. There are several really nice beaches within a half hour as well if you like the water.
Jobs are rough here. State unemployment rate is near 10%. If you want a job on a base you need an in demand skill, really in demand. Those jobs are there but you can't just walk into them. Jobs in general are hard to get. My wife has just now got a part time position after being out of work for 1.5 years. And shes not the kind to want to sit still. I think it almost killed her.
Just a fair warning of what to expect. Not saying you can't get a job but its not like going to North Dakota where you can get one in a week for sure.
Model stores are hard to find. One pretty good one in town and a Micheal's. That's it. A Hobby Lobby in Wilmington and one in Moorehead City both about a hour away. Two good ones in Fayetteville 2 hours or more away.
Cost of living is ok here. Not real cheap (gas tax is highest in any of the surrounding states) but not terrible. Houses are still decent.
Can give more details if you need em. Been here 2 years and plan to be here at least one more.
