Held since March 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 £200,000 sits 73.9% above the 2007 sale of £115,000. On a £-per-square-foot basis, the last sale (£159/sq ft) was about 22.8% below the postcode norm.
