Held since January 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 1996–2008, sale prices on this property compounded at 9.7% per year. Today's modelled estimate of £408,000 sits 69.6% above the 2008 sale of £240,500. On a £-per-square-foot basis, the last sale (£372/sq ft) was about 30.5% above the typical sold price in the postcode. At 60 m² it's 20% larger than the typical home in the postcode (50 m² median across 17 EPCs).
