I work in the public sector and a rare job has come up in an area of the country that I love, it's about an hour and a half drive from our family home, but we could see ourselves moving here after children are through uni/college or when youngest starts secondary.
The job itself sounds good, pay is slightly more than what I am on now. Housing is cheaper there and we could possibly buy a small place near the new job. Initially would probably do an airbnb or hotel near the office. It's a nice area for holidays and breaks that has good accommodation options.
DH has a job in the home area that he wouldn't leave or be able to find elsewhere very easily, so he would stay in the family home with the children for the foreseeable. We have a 7 y/o DS and I have a 15 y/o DD. My thinking is I would be back on weekends and away for three nights per week, hopefully working from home part of the week. DH has been in my DDs life since she was 6 so they know each other well. Grandparents live nearby for extra help.
