Held since April 2008 — that's 18 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 1999–2008, sale prices on this property compounded at 7.8% per year. Today's modelled estimate of £111,000 sits 70.8% above the 2008 sale of £65,000.
