Held since July 2007 — that's 19 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. At 40 m² it sits well below the postcode median (66 m² across 57 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Across 2005–2007, sale prices on this property compounded at 11.6% per year. Today's modelled estimate of £327,000 is 37.4% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£560/sq ft) was about 21.1% above the typical sold price in the postcode.
