Held since September 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. Today's modelled estimate of £691,000 sits 55.3% above the 2008 sale of £445,000. On a £-per-square-foot basis, the last sale (£795/sq ft) was about 53.1% above the typical sold price in the postcode. At 52 m² it sits well below the postcode median (92 m² across 31 EPCs), making it one of the more compact homes locally.
