Held since July 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 1996–2009, sale prices on this property compounded at 8.6% per year. Today's modelled estimate of £344,000 sits 96.6% above the 2009 sale of £175,000. On a £-per-square-foot basis, the last sale (£209/sq ft) was about 27.9% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
