5 GWERN BERTHI ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Blaenau Gwent local authority area over time, sourced from the HPI. The three 5 GWERN BERTHI ROAD sales between August 2005 and October 2024 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 August 2020 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the October 2024 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.
