Held since March 2009 — that's 17 years off the open market, well above the local norm. Across the public record there are 5 sales, relatively high churn for a single property. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 29 m² it sits well below the postcode median (72 m² across 22 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 1997–2009, sale prices on this property compounded at 15.3% per year.
