I'm going to recommend a course of action that makes further demands on a scarce commodity: your time.
If I read you correctly, you're worried because your future seems to be at the mercy of factors beyond your control, ille sunt the jobs market and possibly the housing market.
The most effective way of starting to address your worries would be for you to start sounding out those markets. It would also perhaps give you a sense that you're starting to take your destiny in your own hands.
So first, look for a new job. Don't limit your search geographically: do a nationwide search, do a Europe-wide search, do a worldwide search if necessary.
At the same time, put your house on the market.
After all, you don't have to sell your house if an offer comes along at a time when it's not convenient; and you don't have to take a job just because it's been offered to you. But you'll start to feel more upbeat as you start to see evidence of demand on both fronts. And think how you'll feel if you get the timing right, and you've got a nice redundancy package, a new job lined up and a buyer for your house.
As you see, I think that you should give more serious thought than you appear to have hitherto to the option of moving home. However difficult this process proves to be, you can't allow the housing-market situation to force you into taking a regressive step career-wise. And there is one factor that favours a move: the fact that you have just one person's employment needs to consider.
