PLAS COCH 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 four PLAS COCH sales between March 1995 and August 2019 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 May 2011 sale was for 83% above the HPI. So the extrapolation line tracks at 83% above the HPI over time, until the August 2019 sale, where it rises to 169% above the HPI. The line then continues to track at 169% above the HPI.
