Held since July 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. Across 2002–2007, sale prices on this property compounded at 19.9% per year. Today's modelled estimate of £139,000 sits 51.9% above the 2007 sale of £91,500.
