Held since December 2009 — that's 16 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 £375,000 sits 102.7% above the 2009 sale of £185,000. On a £-per-square-foot basis, the last sale (£142/sq ft) was about 16.4% below the postcode norm. At 121 m² it's 27.4% larger than the typical home in the postcode (95 m² median across 48 EPCs).
