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 166 m² the property is well over the postcode median (75 m² across 14 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 79% of similar EPCs). Today's modelled estimate of £485,000 sits 94% above the 2009 sale of £250,000. On a £-per-square-foot basis, the last sale (£140/sq ft) was about 27.3% below the postcode norm.
