It just feels like a bubble is about to burst and that maybe it's a good time to cash in and sit it out for a few years.
That's calling the market. We did that 8 years ago, but prices continued to rise after we sold.
We did have another house though and my thinking was that I would rather have less debt and fewer assets than a pile of debt and a couple of houses, because I was convinced that interest rates were going to shoot up and the UK housing market was going to tank.
I wouldn't gamble with the roof over my head though and trying to call the top of the market is gambling. If you've done the sums and worked out that the total debt will become un-servisable if interest rates rose to say 6%, then that's making an informed decision on your ability to weather a realistic financial event.
That's what kept me awake and it still bothers me now, although my level of debt is tiny, but I'm unable to work. So my decision proved correct, although for very different reasons.
In hindsight I would have been better off renting the house in Somerset out and using that income stream to pay off all the debt, but I'm now in the position of not caring if the housing market loses 75% of its value overnight. I'm more than happy with that.
I like to read Roubini before bedtime.
