Our house in SE London is now worth an improbable amount. I want to leave my decently paid job and retrain, so three years unpaid with childcare to cover. Our mortgage is on the high side as we've had to borrow extra for major repairs. So the obvious thing is to cash in and move out. But where, where, where? Commutable in less than an hour, place we can buy a four bedroom house for £600,000, some life to it, a place where the newsagents sell more than two copies of the Guardian every day.
