Held since December 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 £322,000 sits 69.5% above the 2009 sale of £190,000. On a £-per-square-foot basis, the last sale (£151/sq ft) was about 48.2% below the postcode norm. At 117 m² it's 19% larger than the typical home in the postcode (98 m² median across 9 EPCs). One historical planning record sits against the property in 2005.
