It hasn't traded since April 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 2003–2007, sale prices on this property compounded at 1% per year. Today's modelled estimate of £142,000 sits 56% above the 2007 sale of £91,000.
