Untraded for 19 years, with the last transfer in August 2007. 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 £156,000 sits 204.2% above the 2007 sale of £51,285. On a £-per-square-foot basis, the last sale (£72/sq ft) was about 66.3% below the postcode norm. At 66 m² it's 29.4% larger than the typical home in the postcode (51 m² median across 40 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
