We did a Simular thing, we had just sent off our visa and decided to put the house on the market, it sold 3 months later! We have only just gone for our medicals, 4 months after we moved out of the house.
We decided to sell the house first so that we could be in a position to go when we wanted.
We were also scared and when all our house was packed up it was a bit worrying, but we know that one way or the other it will all be worth it in the end....
