78 MAES GERDDI 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 78 MAES GERDDI sales from October 2009 and September 2020 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 October 2009 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the September 2020 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.
