Untraded for 19 years, with the last transfer in June 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 36 m² it sits well below the postcode median (65 m² across 10 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £150,000 is 20% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£323/sq ft) was about 83.1% above the typical sold price in the postcode.
