It hasn't traded since November 2009, a hold of 17 years that's notably long for the area. Across the public record there are 5 sales, relatively high churn for a single property. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 1996–2009, sale prices on this property compounded at 9% per year. Today's modelled estimate of £298,000 sits 92.3% above the 2009 sale of £155,000. At 59 m² it's 16.2% smaller than the typical home in the postcode (71 m² median across 36 EPCs). One planning record on file: an extension refused in 2014.
