Held since September 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £164,000 sits 72.6% above the 2009 sale of £95,000. On a £-per-square-foot basis, the last sale (£105/sq ft) was about 24.9% above the typical sold price in the postcode. At 84 m² it's 20% larger than the typical home in the postcode (70 m² median across 25 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs).
