It hasn't traded since December 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 98 m² the property is well over the postcode median (64 m² across 7 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Today's modelled estimate of £238,000 is 48.8% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£151/sq ft) was about 26.5% above the typical sold price in the postcode.
