Held since August 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 £985,000 sits 97% above the 2007 sale of £499,999. On a £-per-square-foot basis, the last sale (£241/sq ft) was about 26.2% below the postcode norm. 2 planning records sit against the property, 1 approved, 1 refused. Past consents include a garage conversion, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs).
