Quality real estate in the UK has retained more of its value over the past 18 months than the more average or less well maintained and located property, according to Savills Research.

On average, prices for the best properties have decreased by an eighth, some -11.81%, of their value from the peak of the property boom in 2007. While those blighted by factors such as location, noise pollution or neighbours have dropped by more than a quarter at -25.47%.

The sharpest falls have been seen in blighted properties priced up to £500,000 which have now fallen by -29% from the peak. By contrast, the best properties in the same price band lost only just over -14% of their value.

A similar 15% divide is seen between the best and the rest at the top end of the market, where the best properties over £2m have dropped by just -11% and the worst by -26%.
