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 76% of similar EPCs). Across 1996–2007, sale prices on this property compounded at 11.7% per year. Today's modelled estimate of £170,000 is 29.8% above the 2007 sale price.
