It hasn't traded since December 2009, a hold of 16 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 139 m² the property is well over the postcode median (105 m² across 13 EPCs), placing it in the larger end of the local stock. Across 1996–2009, sale prices on this property compounded at 6.1% per year. Today's modelled estimate of £675,000 sits 95.1% above the 2009 sale of £346,000.
