Held since January 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 1998–2008, sale prices on this property compounded at 9.3% per year. Today's modelled estimate of £410,000 sits 78.3% above the 2008 sale of £230,000. On a £-per-square-foot basis, the last sale (£319/sq ft) was about 27.6% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs).
