Held since July 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. Across 2003–2008, sale prices on this property compounded at 1.2% per year. Today's modelled estimate of £203,000 sits 61.1% above the 2008 sale of £126,000. On a £-per-square-foot basis, the last sale (£300/sq ft) was about 80.2% above the typical sold price in the postcode. At 39 m² it sits well below the postcode median (84 m² across 49 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs).
