It hasn't traded since December 2007, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1996–2007, sale prices on this property compounded at 11.3% per year. Today's modelled estimate of £427,000 sits 90.6% above the 2007 sale of £224,000. On a £-per-square-foot basis, the last sale (£267/sq ft) was about 27.3% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs).
