Untraded for 17 years, with the last transfer in December 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 £336,000 sits 72.3% above the 2008 sale of £195,000. On a £-per-square-foot basis, the last sale (£503/sq ft) was about 104.5% above the typical sold price in the postcode.
