Held since April 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. At 110 m² the property is well over the postcode median (84 m² across 15 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £132,000 sits 78.4% above the 2009 sale of £74,000. On a £-per-square-foot basis, the last sale (£62/sq ft) was about 20.2% above the typical sold price in the postcode.
