Held since October 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. At 121 m² it's 23.5% larger than the typical home in the postcode (98 m² median across 27 EPCs). Its energy rating outperforms most of the postcode (better than 89% of similar EPCs). Today's modelled estimate of £292,000 is 35.2% above the 2007 sale price.
