It hasn't traded since October 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 £102,000 is 45.7% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£160/sq ft) was about 23.4% below the postcode norm. At 41 m² it's 20.1% smaller than the typical home in the postcode (51 m² median across 38 EPCs).
