You will wait to move until after he finishes "A" School. He will find out during "A" School where he will be stationed and if he has accompanied orders. Once he knows where he will be stationed, then you will be able to find out more about the housing options available. There is usually a waiting list for base housing if he is eligible for that. He will have to look for housing when the time comes. There are discussions within Girlfriends, Fiances, and Wives of Sailors on how to make the move when the time comes. Right now take things one step at a time and prepare for BC. See Things to Do in the Last Month before Your Future Sailor Leaves for....
I left info for you on your My Page.
You are very welcome.
Also realize that even though his "A" School is for 8 weeks that he could be there longer if he must wait for a class to form and is in Holding for a while. What is his rating (job/specialty) going to be? I don't see any with "A" School in GL that last 8 weeks.
A school is always longer than the stated seat time on paper. He'll have a week of indoctrination, and yes, he may have to wait to class up. Shorter schools have shorter wait times, so I'd anticipate about nine to ten weeks. But stay flexible!
With a very short school, they may receive orders in boot camps. With his school, maybe not, but it would not be impossible.
Right now, I'd suggest you prepare for a move. Start by throwing away or donating anything you do not need, get your important papers organized. If you think you may have to drive to his new duty station (the Navy doesn't ship cars), get the vehicle ready for a road trip. You know you'll be moving, so start prepping early.
