Held since December 2008 — that's 17 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 123 m² the property is well over the postcode median (55 m² across 8 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £646,000 sits 158.4% above the 2008 sale of £250,000. On a £-per-square-foot basis, the last sale (£189/sq ft) was about 38.7% below the postcode norm.
