Held since November 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 26 m² it sits well below the postcode median (51 m² across 18 EPCs), making it one of the more compact homes locally. Across 1996–2007, sale prices on this property compounded at 13.1% per year. Today's modelled estimate of £227,000 is 16.4% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£697/sq ft) was about 235.2% above the typical sold price in the postcode.
