Held since May 2008 — that's 18 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 90 m² the property is well over the postcode median (50 m² across 20 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £520,000 sits 131.1% above the 2008 sale of £225,000. On a £-per-square-foot basis, the last sale (£232/sq ft) was about 35.5% below the postcode norm.
