Held since January 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 55 m² it sits well below the postcode median (100 m² across 12 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £439,000 is 47.3% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£503/sq ft) was about 37.6% above the typical sold price in the postcode.
