Held since April 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. Today's modelled estimate of £105,000 sits 61.5% above the 2007 sale of £65,000. On a £-per-square-foot basis, the last sale (£72/sq ft) was about 29.7% above the typical sold price in the postcode.
