It hasn't traded since January 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 86 m² the property is well over the postcode median (61 m² across 7 EPCs), placing it in the larger end of the local stock. Across 2002–2007, sale prices on this property compounded at 15.3% per year. Today's modelled estimate of £152,000 is 28.8% above the 2007 sale price.
