It hasn't traded since October 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 52 m² the property is well over the postcode median (38 m² across 75 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £294,000 sits 267.5% above the 2009 sale of £80,000. On a £-per-square-foot basis, the last sale (£143/sq ft) was about 68.1% below the postcode norm.
