Today's modelled estimate of £111,000 is 12.6% below the 2007 sale of £126,995, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£288/sq ft) was about 22.6% above the typical sold price in the postcode. Held since November 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. It lags the bulk of the postcode on energy efficiency (less efficient than 81% of similar EPCs).
