It hasn't traded since March 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. Across 2003–2009, sale prices on this property compounded at 4.2% per year. Today's modelled estimate of £106,000 sits 65.6% above the 2009 sale of £64,000.
