Today's modelled estimate of £187,000 is 21.1% below the 2007 sale of £237,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£344/sq ft) was about 27.7% above the typical sold price in the postcode. 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 64 m² it's 18.5% larger than the typical home in the postcode (54 m² median across 55 EPCs).
