Today's modelled estimate of £185,000 is 38.3% below the 2007 sale of £300,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£569/sq ft) was about 330.6% above the typical sold price in the postcode. Held since August 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.
