Held since June 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 43 m² it sits well below the postcode median (97 m² across 15 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 87% of similar EPCs). Across 1996–2007, sale prices on this property compounded at 11.7% per year. Today's modelled estimate of £205,000 is 30.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£339/sq ft) was about 16.9% above the typical sold price in the postcode.
