Held since May 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 366 m² the property is well over the postcode median (134 m² across 5 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £2,771,000 is 45.8% above the 2009 sale price.
