It hasn't traded since October 2008, 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. At 72 m² it's 21% larger than the typical home in the postcode (60 m² median across 64 EPCs). Today's modelled estimate of £192,000 is 24.7% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£199/sq ft) was about 23.8% below the postcode norm.
