Held since February 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 £112,000 sits 397.8% above the 2007 sale of £22,500. On a £-per-square-foot basis, the last sale (£29/sq ft) was about 60.5% below the postcode norm. One planning record on file: an extension approved in 2008. Past consents include an extension, meaningful when judging how the property has evolved. Its energy rating outperforms most of the postcode (better than 74% of similar EPCs).
