Held since November 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 £359,000 sits 63.2% above the 2009 sale of £220,000. At 89 m² it's 17.4% smaller than the typical home in the postcode (108 m² median across 19 EPCs).
