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. Across 2003–2007, sale prices on this property compounded at 4.7% per year. Today's modelled estimate of £249,000 sits 61.7% above the 2007 sale of £154,000. On a £-per-square-foot basis, the last sale (£251/sq ft) was about 15.5% below the postcode norm. At 57 m² it sits well below the postcode median (83 m² across 72 EPCs), making it one of the more compact homes locally.
