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. Across 2001–2009, sale prices on this property compounded at 9% per year. Today's modelled estimate of £236,000 sits 50.3% above the 2009 sale of £157,000. On a £-per-square-foot basis, the last sale (£304/sq ft) was about 35.8% below the postcode norm. At 48 m² it's 15.8% smaller than the typical home in the postcode (57 m² median across 37 EPCs).
