Held since July 2007 — that's 19 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. Across 2000–2007, sale prices on this property compounded at 11.4% per year. Today's modelled estimate of £332,000 sits 53.3% above the 2007 sale of £216,500. On a £-per-square-foot basis, the last sale (£214/sq ft) was about 27.7% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 70% of similar EPCs).
