Held since August 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £273,000 sits 143.8% above the 2009 sale of £112,000. On a £-per-square-foot basis, the last sale (£106/sq ft) was about 15.7% below the postcode norm. One planning record on file: an extension approved in 2009. Past consents include an extension, meaningful when judging how the property has evolved.
