Untraded for 19 years, with the last transfer in November 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 £643,000 sits 131.7% above the 2007 sale of £277,500. On a £-per-square-foot basis, the last sale (£205/sq ft) was about 31.8% below the postcode norm. 3 planning records sit against the property, 0 approved, 3 refused.
