21 TREM Y DON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The three 21 TREM Y DON sales between March 2005 and August 2021 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 2007 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the August 2021 sale, where it rises to 35% above the HPI. The line then continues to track at 35% above the HPI.
