Held since March 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. At 58 m² it sits well below the postcode median (140 m² across 6 EPCs), making it one of the more compact homes locally. Across 2000–2008, sale prices on this property compounded at 11% per year. Today's modelled estimate of £260,000 is 40.6% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£296/sq ft) was about 90% above the typical sold price in the postcode.
