Today's modelled estimate of £103,000 is 18.9% below the 2007 sale of £126,995, a rare downward gap that often correlates with deferred maintenance or unfinished works. It hasn't traded since September 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. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
