Held since February 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 2003–2008, sale prices on this property compounded at 12.4% per year. Today's modelled estimate of £119,000 sits 83.1% above the 2008 sale of £65,000. On a £-per-square-foot basis, the last sale (£74/sq ft) was about 16.2% below the postcode norm. At 82 m² it's 29.1% larger than the typical home in the postcode (64 m² median across 22 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs).
