KEYNES HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two KEYNES HOUSE sales from November 2011 and August 2022 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 November 2011 sale was for 315% above the HPI. So the extrapolation line tracks at 315% above the HPI over time, until the August 2022 sale, where it falls to 220% above the HPI. The line then continues to track at 220% above the HPI.
