Held since June 2008 — that's 18 years off the open market, well above the local norm. 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 (68 m² across 12 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £166,000 is 14.5% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£132/sq ft) was about 15.5% below the postcode norm.
