Held since November 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 £540,000 sits 77% above the 2009 sale of £305,000. On a £-per-square-foot basis, the last sale (£277/sq ft) was about 26.2% below the postcode norm. At 102 m² it's 29.4% larger than the typical home in the postcode (79 m² median across 3 EPCs).
