Held since July 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. At 46 m² the property is well over the postcode median (30 m² across 40 EPCs), placing it in the larger end of the local stock. Across 2006–2009, sale prices on this property compounded at 3.6% per year. Today's modelled estimate of £468,000 is 28.2% above the 2009 sale price.
