It hasn't traded since June 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. Across 2000–2007, sale prices on this property compounded at 11.3% per year. Today's modelled estimate of £181,000 is 47.8% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£344/sq ft) was about 51.5% above the typical sold price in the postcode.
