It hasn't traded since August 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 87 m² the property is well over the postcode median (50 m² across 51 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs). Across 2003–2009, sale prices on this property compounded at -3.8% per year. Today's modelled estimate of £187,000 sits 139.7% above the 2009 sale of £78,000. On a £-per-square-foot basis, the last sale (£83/sq ft) was about 37.9% below the postcode norm.
