Held since July 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 £249,000 sits 57.1% above the 2009 sale of £158,500. On a £-per-square-foot basis, the last sale (£144/sq ft) was about 40.6% below the postcode norm. At 102 m² it's 22.9% larger than the typical home in the postcode (83 m² median across 5 EPCs).
