Untraded for 16 years, with the last transfer in December 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Sale prices here have outpaced England HPI: 24.6% per year against 0% for the wider region. Today's modelled estimate of £495,000 sits 98% above the 2009 sale of £249,995. On a £-per-square-foot basis, the last sale (£170/sq ft) was about 46.9% below the postcode norm. At 137 m² the property is well over the postcode median (73 m² across 17 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2008. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved.
