It hasn't traded since May 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 38 m² it sits well below the postcode median (70 m² across 47 EPCs), making it one of the more compact homes locally. Across 2005–2007, sale prices on this property compounded at 9% per year. Today's modelled estimate of £190,000 is 31.1% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£354/sq ft) was about 79.7% above the typical sold price in the postcode.
