Held since October 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 £450,000 sits 50% above the 2007 sale of £299,995. One planning record on file: an extension refused in 2008.
