Held since December 2009 — that's 16 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.

Across 2007–2009, sale prices on this property compounded at -29.3% per year. Today's modelled estimate of £196,000 sits 180% above the 2009 sale of £70,000.
