Held since October 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2001–2008, sale prices on this property compounded at 5.5% per year. Today's modelled estimate of £563,000 sits 60.9% above the 2008 sale of £350,000. On a £-per-square-foot basis, the last sale (£542/sq ft) was about 35.4% above the typical sold price in the postcode. At 60 m² it sits well below the postcode median (100 m² across 14 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
