Held since June 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. At 35 m² it sits well below the postcode median (69 m² across 4 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £493,000 sits 57.8% above the 2009 sale of £312,500. On a £-per-square-foot basis, the last sale (£829/sq ft) was about 29.4% below the postcode norm.
