Held since April 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. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs). Today's modelled estimate of £126,000 is 20% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£227/sq ft) was about 58.3% below the postcode norm.
