Held since March 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 £191,000 sits 229.3% above the 2009 sale of £58,000. On a £-per-square-foot basis, the last sale (£104/sq ft) was about 35% below the postcode norm. At 52 m² it's 23% smaller than the typical home in the postcode (68 m² median across 14 EPCs).
