Held since August 2008 — that's 18 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 40 m² it's 20% smaller than the typical home in the postcode (50 m² median across 19 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £103,000 is 17% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£204/sq ft) was about 45.2% above the typical sold price in the postcode.
