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. Across 1995–2007, sale prices on this property compounded at 23.7% per year. Today's modelled estimate of £312,000 sits 60% above the 2007 sale of £195,000. At 57 m² it sits well below the postcode median (89 m² across 38 EPCs), making it one of the more compact homes locally.
