Untraded for 18 years, with the last transfer in June 2008. 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 £397,000 sits 126.9% above the 2008 sale of £175,000. On a £-per-square-foot basis, the last sale (£285/sq ft) was about 22.7% below the postcode norm. At 57 m² it's 28.3% smaller than the typical home in the postcode (80 m² median across 58 EPCs).
