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. At 101 m² the property is well over the postcode median (76 m² across 9 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Today's modelled estimate of £201,000 is 19.6% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£155/sq ft) was about 25.4% below the postcode norm.
