It hasn't traded since September 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. At 47 m² it's 17.5% larger than the typical home in the postcode (40 m² median across 85 EPCs). Today's modelled estimate of £177,000 is 22.1% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£287/sq ft) was about 49% above the typical sold price in the postcode.
