Held since July 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 £1,655,000 sits 166.9% above the 2009 sale of £620,000. On a £-per-square-foot basis, the last sale (£177/sq ft) was about 47.2% below the postcode norm. 7 planning records sit against the property, 5 approved, 2 refused. Past consents include a porch, meaningful when judging how the property has evolved.
