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. Today's modelled estimate of £106,000 sits 63.1% above the 2008 sale of £65,000. On a £-per-square-foot basis, the last sale (£76/sq ft) was about 158.6% above the typical sold price in the postcode. At 79 m² it's 16.2% larger than the typical home in the postcode (68 m² median across 22 EPCs).
