Held since May 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 32 m² it sits well below the postcode median (69 m² across 42 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 79% of similar EPCs). Across 2000–2007, sale prices on this property compounded at 16.1% per year. Today's modelled estimate of £151,000 is 11.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£392/sq ft) was about 213% above the typical sold price in the postcode.
