Held since November 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. Across 1999–2009, sale prices on this property compounded at 10.6% per year. Today's modelled estimate of £372,000 sits 52.5% above the 2009 sale of £244,000.
