Today's modelled estimate of £298,000 is 20.5% below the 2008 sale of £375,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£345/sq ft) was about 42.5% above the typical sold price in the postcode. Held since May 2008 — that's 18 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 101 m² the property is well over the postcode median (68 m² across 49 EPCs), placing it in the larger end of the local stock.
