Held since September 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 55 m² it sits well below the postcode median (90 m² across 23 EPCs), making it one of the more compact homes locally. Across 2001–2009, sale prices on this property compounded at 8.1% per year.
