It hasn't traded since March 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.

Today's modelled estimate of £243,000 is 34.3% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£366/sq ft) was about 37.1% above the typical sold price in the postcode.
