Held since April 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 53 m² it sits well below the postcode median (104 m² across 23 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 74% of similar EPCs). Across 2002–2007, sale prices on this property compounded at 13.1% per year. Today's modelled estimate of £173,000 is 30.1% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£233/sq ft) was about 76.7% above the typical sold price in the postcode.
