I live in Maryland and would never encourage anyone to move here. In fact I’d love to live down south but all my family’s here. Housing is ridiculously expensive and traffics a nightmare. You’d have to evaluate if it was worth it to your family. Your kids would have to be uprooted and at that age they’d probably not be happy about it. There are several nice areas around ft mead but they’re very expensive. Even a not so nice brick row house in Baltimore city sells for over $200,000 now. We’re the richest state in the country (because so many politicians live here) and that is reflected in the increased costs of housing, taxes and everything else. It is nice to be near DC but not sure it’s worth living here. If you decide to live here you could work as a nurse in Dc they pay more than Maryland.
Another Marylander here...I'm afraid Disneydreamer1980 is not wrong. My husband works occasionally on Ft. Meade, we live on the Eastern Shore. Housing costs are for sure higher over there, you could move to Queen Anne's County/ Stevensville area but you'd have shore traffic to contend with. Ok schools, and there is one private school in Centreville that I can highly recommend. Property taxes are high, we pay $6K per year in property tax (20 acre farm, part in agriculture, house is newer but not a massive mcmansion, it's a cape cod at about 3K sq feet) $2K per year on homeowners insurance (I don't think that is terrible) and my last electric bill was $493

We don't have anything in Maryland along the lines of what GA has in regards to the college benefits for your kids, however Delaware does. Wish MD did... What MD & northern VA do have is a lot of private military contractors, so there could possibly be many opportunities for jobs. Of course, Northern VA is not exactly a cheap place to live either.
Good luck to you & your husband in your decision making!
(my parents moved us from New Jersey to rural Delaware when I was 12 - I survived just fine)
