Susan, I am afraid I cannot speak to your immigration question since this is not my area of expertise. I would suggest you consult an immigration attorney for assistance in this matter. As to your real estate inquiry, I am not able to tell you much. The answer would depend on where you were moving, what the market was like at that point, and the type of accommodation you are looking for. If you google average cost of family homes in the UK is about 300 grand. Good luck!
