Held since March 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. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). Today's modelled estimate of £135,000 is 30.2% above the 2009 sale price.
