It hasn't traded since April 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 2000–2008, sale prices on this property compounded at 12.5% per year. Today's modelled estimate of £111,000 is 23.3% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£149/sq ft) was about 124.4% above the typical sold price in the postcode.
