John,
I can't answer that one for you. You must just be aware that the promised villa may well not occur for quite a while. I was advised only tonight of yet another of my coursemates who is having marital problems since arriving here, a major part of the problem is the lack of permanent housing for us.
All I can say is...if you are in a job at the moment, and are coming here for the bigger plane only, then think if the plane is worth your marriage. The strain you will be placed under, due to no fault of your own, is tremendous. If you don't have a job, or you are about to be laid off, sure, then come along, as this is better than no work at all.
Good luck in your decisionmaking. If you are aware of some of the pitfalls along the way, and your family is as well, you may be able to somehow prepare yourself.
