Held since August 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 115 m² the property is well over the postcode median (81 m² across 22 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £375,000 sits 72% above the 2009 sale of £218,000. On a £-per-square-foot basis, the last sale (£176/sq ft) was about 19.9% below the postcode norm.
