Held since January 2007 — that's 20 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 £336,000 sits 69.7% above the 2007 sale of £198,000. On a £-per-square-foot basis, the last sale (£341/sq ft) was about 40.9% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs).
