Having been observing the market closely for a few months, it does look like the asking prices for many £1-3M properties are being reduced. When you consider inflation is running at 3% in the UK currently it's easy to see house prices fall by 10% this year.
On the high end, it's easy to see that figure reach 20-30%. At the entry level of the market though, there is still so much pent up demand for housing I personally can't see any significant falls, just growth flatlining.
