Held since December 2009 — that's 16 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 £218,000 sits 59.1% above the 2009 sale of £137,000. On a £-per-square-foot basis, the last sale (£322/sq ft) was about 18.4% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
