Held since October 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 £263,000 sits 122.9% above the 2009 sale of £118,000. On a £-per-square-foot basis, the last sale (£102/sq ft) was about 43.9% below the postcode norm. At 108 m² it's 20% larger than the typical home in the postcode (90 m² median across 25 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 72% of similar EPCs).
