My personal, humble, opinion is that you would be bonkers to sell your home for the rather remote prospect of making huge gains if the market goes bust. It is highly, highly unlikely that house prices will fall and certainly not in the way experienced in the late 80s/early 90s. Back then, interest rates were hiked up to 15% to try and cool the economy down but instead the housing market imploded spectacularly because people could not afford their mortgage and other credit repayments, forcing them to sell (or be repossessed) resulting in a flood of property on the market, hence seeing prices crash. That�s not going to happen now. Yes, property prices are high, but interest rates remain relatively low and they are not predicted to rise further than to 5.5% over the next 9 months or so and they will then slowly come back down again (though probably not to the 3.5% we had). Look at what the mortgage provider market is doing � they are still offering competitive fixed rate/discount rate deals because they know that interest rates aren�t likely to increase much further. Provided interest rates remain at these low levels, people will be able to continue their afford their mortgage and other commitments. On a purely cynical level, there�s a general election next year so I think the govt will pull out all the stops to prevent a property bust situation.
