It hasn't traded since June 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. Today's modelled estimate of £146,000 sits 276.8% above the 2009 sale of £38,750. On a £-per-square-foot basis, the last sale (£53/sq ft) was about 58.6% below the postcode norm.
