Held since September 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 £513,000 sits 113.8% above the 2009 sale of £240,000. On a £-per-square-foot basis, the last sale (£245/sq ft) was about 20.9% below the postcode norm. One historical planning record sits against the property in 2017.
