I'm part-time, term-time and we are hoping to pay the mortgage off in about 3 years. By that point our first child will be about 2 years away from going to university. We'll end up using the money from the mortgage to help him at uni if he goes or save it into my husband's pension I think as his is very small currently.
Despite that our lives will remain the same, I can't wait until it's paid off as I think it just removes so much pressure as it means that we could survive on one income, which we couldn't do currently.
If I wasn't part-time already though I think I'd definitely go part-time, but then I'm not fond of my job. When I enjoyed it, in the dim and distant past, I would have happily kept on working.
