Too many people think about a house as an investment first and home second and that is why we are in this mess.
I think you have to consider both options.
Personally I just agreed last week to buy a new home, we'll probably take a hefty hit over the next year or so (say a £20-30k loss) but I decided that quality of life improvement was worth that. I've spent the vast majority of my life being frugal and have decided to start splashing out for once, even if I'm getting ripped off.
