It hasn't traded since January 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2003–2008, sale prices on this property compounded at 11.1% per year. Today's modelled estimate of £102,000 sits 64.5% above the 2008 sale of £62,000. On a £-per-square-foot basis, the last sale (£101/sq ft) was about 47.6% above the typical sold price in the postcode. At 57 m² it sits well below the postcode median (96 m² across 36 EPCs), making it one of the more compact homes locally.
