You can request a DLA(dislocation allowance) to pay for the move. When my husband got orders for Yongsan, we were granted one to move us from our home to my parent's house in Southern Ohio until the CS went through.
Is Casey his first duty station? If not are you located in on post or off post housing? Is he going to try for a Command Sponsorship?
Will they cover the full cost? No, but with the DLA help with the move, yes. Keep all your receipts.
