The below graph shows the average semi-detached house price in the Breckland local authority area over time, sourced from the HPI. The three 31 WILLIAM COWPER CLOSE sales between April 2007 and November 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the December 2014 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the November 2025 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.
