Untraded for 18 years, with the last transfer in October 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 27 m² it sits well below the postcode median (129 m² across 28 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £111,000 is 38.7% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£275/sq ft) was about 29.5% above the typical sold price in the postcode.
