Held since July 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £570,000 sits 86.9% above the 2008 sale of £305,000. On a £-per-square-foot basis, the last sale (£346/sq ft) was about 20.9% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 79% of similar EPCs).
