Held since September 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 25 m² it sits well below the postcode median (41 m² across 38 EPCs), making it one of the more compact homes locally. Across 2002–2007, sale prices on this property compounded at 6.8% per year. Today's modelled estimate of £105,000 is 40% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£279/sq ft) was about 15.9% above the typical sold price in the postcode.
