12 PEN Y DYFFRYN Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Merthyr Tydfil local authority area over time, sourced from the HPI. The two 12 PEN Y DYFFRYN sales from March 2013 and December 2017 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 2013 sale was for 137% above the HPI. So the extrapolation line tracks at 137% above the HPI over time, until the December 2017 sale, where it falls to 109% above the HPI. The line then continues to track at 109% above the HPI.
