Untraded for 19 years, with the last transfer in January 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2004–2007, sale prices on this property compounded at 10% per year. Today's modelled estimate of £241,000 sits 55.5% above the 2007 sale of £155,000. On a £-per-square-foot basis, the last sale (£686/sq ft) was about 53.2% above the typical sold price in the postcode. At 21 m² it sits well below the postcode median (82 m² across 22 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
