It hasn't traded since May 2007, a hold of 19 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. Today's modelled estimate of £263,000 sits 55.2% above the 2007 sale of £169,500. On a £-per-square-foot basis, the last sale (£258/sq ft) was about 62.5% above the typical sold price in the postcode. At 61 m² it sits well below the postcode median (99 m² across 26 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
