Untraded for 19 years, with the last transfer in July 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £460,000 sits 55.9% above the 2007 sale of £295,000. At 48 m² it sits well below the postcode median (87 m² across 35 EPCs), making it one of the more compact homes locally.
