It hasn't traded since May 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 148 m² the property is well over the postcode median (66 m² across 69 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 2008–2009, sale prices on this property compounded at 52.2% per year. Today's modelled estimate of £404,000 is 15.4% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£220/sq ft) was about 34.5% below the postcode norm.
