This one probably wont sit so well, but it's the real deal!
The armed forces does give some consideration for the marital status of the recruite, but their mission is to get your spouse trained. Basic, Tech School, Whatever! Them first, you last. Until he's finished his training, things will be a crap shoot. Depending on his career field, he could be bouncing around the country/world on a moments notice! Until you hear the words, " Duty Station", I suggest you just hunker down at your present location, relax and save your money! Once he has a duty station, the service allows for moving expenses. Until then everything you do will be your own expense! SC may be cheaper then Ca, but it still isn't cheap!
Each base has it's own set of rules for base housing, who can get it, who can't, usually based on availability. Rank plays a big part also! Pets, no pets, or maybe even size retriction. You probably won't get a big response to your questions, because your spouse is in limbo until he gets a duty station.
Sorry for no definitive answers, but there just not available at this time.
