Held since August 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. Across 2006–2007, sale prices on this property compounded at 17.9% per year. Today's modelled estimate of £130,000 is 16.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£203/sq ft) was about 18.3% above the typical sold price in the postcode. At 51 m² it's 21.5% smaller than the typical home in the postcode (65 m² median across 29 EPCs).
