Untraded for 19 years, with the last transfer in June 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 75 m² the property is well over the postcode median (48 m² across 28 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £168,000 is 24.4% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£167/sq ft) was about 25.1% below the postcode norm.
