Held since December 2007 — 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 sits well below the postcode median (60 m² across 19 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £267,000 is 44.3% above the 2007 sale price.
