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. At 138 m² the property is well over the postcode median (100 m² across 9 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £599,000 sits 110.2% above the 2009 sale of £285,000. On a £-per-square-foot basis, the last sale (£192/sq ft) was about 20.3% below the postcode norm.
