It hasn't traded since September 2007, a hold of 19 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. At 32 m² it sits well below the postcode median (49 m² across 22 EPCs), making it one of the more compact homes locally. Across 2000–2007, sale prices on this property compounded at 22.6% per year. Today's modelled estimate of £104,000 is 15.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£261/sq ft) was about 122% above the typical sold price in the postcode.
