Held since October 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 86 m² the property is well over the postcode median (59 m² across 24 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £366,000 sits 121.8% above the 2007 sale of £165,000. On a £-per-square-foot basis, the last sale (£179/sq ft) was about 40.9% below the postcode norm.
