Held since May 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 £164,000 is 31.2% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£168/sq ft) was about 16.1% above the typical sold price in the postcode. At 69 m² it's 22.5% smaller than the typical home in the postcode (89 m² median across 34 EPCs).
