Held since May 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 46 m² it's 20.3% smaller than the typical home in the postcode (57 m² median across 18 EPCs). Across 2003–2007, sale prices on this property compounded at 6.1% per year. Today's modelled estimate of £123,000 is 32.3% above the 2007 sale price.
