It hasn't traded since April 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 177 m² the property is well over the postcode median (86 m² across 10 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £413,000 is 29.1% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£168/sq ft) was about 15.3% below the postcode norm.
