Held since January 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 £278,000 sits 113.8% above the 2009 sale of £130,000. On a £-per-square-foot basis, the last sale (£178/sq ft) was about 18.5% below the postcode norm. At 68 m² it's 20.4% larger than the typical home in the postcode (56 m² median across 36 EPCs).
