Today's modelled estimate of £206,000 is 17.6% below the 2008 sale of £250,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£327/sq ft) was about 35.1% above the typical sold price in the postcode. Held since April 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.
