Today's modelled estimate of £111,000 is 22.9% below the 2008 sale of £143,950, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£209/sq ft) was about 35% above the typical sold price in the postcode. It hasn't traded since May 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.
