England?

My husband's job posted an opening for someone over in Sheffield, England for a two year position. The position is currently in development and probably won't start for a year. Originally when I was searching for a career, I wanted to go with one of the then Big Five accounting firms to be able to possibly take a short term assignment overseas. The decision would have been a lot more simple years ago, before my son started school. However, based on his kindergarten performance, maybe going away for two years would give him a fresh start when he got back. My husband thinks it would be amusing to have kids with English accents. My main problem is I wouldn't want to give up my house. Most people either sell or rent their houses when they go, I wouldn't want to do either. I can't stand the thought of someone I don't know living in my house. I like my house and would want to return to it after the two year period. Of course, the idea of putting my career on hold doesn't both me much. The company would provide housing and if we decided the public schools wouldn't work, I could teach from home. It's definitely a possibility. That is if he's the one selected to go.
