It hasn't traded since August 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. At 102 m² the property is well over the postcode median (54 m² across 3 EPCs), placing it in the larger end of the local stock.
