It hasn't traded since September 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 2008–2009, sale prices on this property compounded at -3.8% per year. Today's modelled estimate of £110,000 sits 115.7% above the 2009 sale of £51,000. On a £-per-square-foot basis, the last sale (£88/sq ft) was about 34.3% above the typical sold price in the postcode. At 54 m² it sits well below the postcode median (81 m² across 14 EPCs), making it one of the more compact homes locally.
