It hasn't traded since August 2007, a hold of 19 years that's notably long for the area. 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 £198,000 sits 209.4% above the 2007 sale of £64,000. On a £-per-square-foot basis, the last sale (£57/sq ft) was about 48.8% below the postcode norm. 2 planning records sit against the property, 1 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 104 m² it's 26.8% larger than the typical home in the postcode (82 m² median across 45 EPCs).
