It hasn't traded since December 2007, 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. At 26 m² it sits well below the postcode median (65 m² across 14 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £100,000 is 42.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£250/sq ft) was about 112.5% above the typical sold price in the postcode.
