It hasn't traded since November 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 2009–2009, sale prices on this property compounded at 17.3% per year. Today's modelled estimate of £1,033,000 sits 79.7% above the 2009 sale of £575,000.
