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. Today's modelled estimate of £328,000 sits 64% above the 2009 sale of £200,000. 3 planning records sit against the property, 0 approved, 3 refused. At 79 m² it's 29.5% smaller than the typical home in the postcode (112 m² median across 5 EPCs).
Recommended upgrades on file would lift this property by multiple EPC bands.
