Held since May 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. Today's modelled estimate of £293,000 sits 74.4% above the 2008 sale of £168,000. On a £-per-square-foot basis, the last sale (£233/sq ft) was about 39.2% above the typical sold price in the postcode.
