Held since June 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 74 m² the property is well over the postcode median (56 m² across 36 EPCs), placing it in the larger end of the local stock. Across 2004–2007, sale prices on this property compounded at 5.2% per year. Today's modelled estimate of £257,000 sits 83.6% above the 2007 sale of £140,000.
