Held since October 2007 — that's 19 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 130 m² the property is well over the postcode median (56 m² across 39 EPCs), placing it in the larger end of the local stock.
