Right Move announced today that prices have actually risen in the UK.
Rightmove only track asking prices on their own website. Having experienced the ability of the average (i.e. useless) UK REA, and the even dumber gullibility (myself included) to believe UK REA valuations, I take any Rightmove pricing index with a pinch of salt. The only index I go off now is the Land Registry which tracks actual selling prices. The only problem is that it is usually 3 months out of date.
