Held since May 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 100 m² the property is well over the postcode median (76 m² across 24 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £169,000 sits 160% above the 2009 sale of £65,000. On a £-per-square-foot basis, the last sale (£60/sq ft) was about 37.1% below the postcode norm. One historical planning record sits against the property in 2017.
