if prices have decreased by 8% in some areas of London, and only 2% in others, is it likely this pattern will continue if prices fall further. i.e some areas de-value quicker than others?
I should think so. What tends to happen in a rising market is that all the good stuff goes up in value first, then once that becomes unaffordable then all the dross goes up. Come the slup the first to go down is all the dross.
