Held since March 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. Today's modelled estimate of £237,000 is 43.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£229/sq ft) was about 45.2% above the typical sold price in the postcode. At 67 m² it's 20.2% smaller than the typical home in the postcode (84 m² median across 3 EPCs).
