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 £120,000 sits 162% above the 2008 sale of £45,800. At 58 m² it's 15.3% smaller than the typical home in the postcode (69 m² median across 6 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).
