Held since August 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 48 m² it sits well below the postcode median (76 m² across 5 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 £114,000 sits 79.5% above the 2007 sale of £63,500. On a £-per-square-foot basis, the last sale (£122/sq ft) was about 106.1% above the typical sold price in the postcode.
