Held since June 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 78% of similar EPCs). Today's modelled estimate of £105,000 is 12.3% above the 2007 sale price.
