Held since February 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 2002–2008, sale prices on this property compounded at 8% per year. Today's modelled estimate of £142,000 sits 51.1% above the 2008 sale of £94,000. On a £-per-square-foot basis, the last sale (£171/sq ft) was about 34.6% above the typical sold price in the postcode.
