Held since April 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 2002–2008, sale prices on this property compounded at 13.4% per year. Today's modelled estimate of £110,000 sits 100% above the 2008 sale of £55,000. On a £-per-square-foot basis, the last sale (£222/sq ft) was about 69% above the typical sold price in the postcode. At 23 m² it's 22.5% smaller than the typical home in the postcode (30 m² median across 56 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).
