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. At 71 m² it's 18.3% larger than the typical home in the postcode (60 m² median across 16 EPCs). Today's modelled estimate of £263,000 is 44.1% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£239/sq ft) was about 15.8% below the postcode norm.
