Today's modelled estimate of £218,000 is 11.4% below the 2009 sale of £246,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£336/sq ft) was about 365.7% above the typical sold price in the postcode. Held since August 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
