ISGAER Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two ISGAER sales from March 1997 and April 2018 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 March 1997 sale was for 62% above the HPI. So the extrapolation line tracks at 62% above the HPI over time, until the April 2018 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.
