26 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 two 26 GWERN BERTHI ROAD sales from December 2002 and May 2013 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 December 2002 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the May 2013 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 26 GWERN BERTHI ROAD be worth now?

This is based on house price inflation of 94.8%, between May 2013 and June 2025, for terraced houses, in the Blaenau Gwent local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 94.8% inflationary increase is applied to the most recent sale price for 26 GWERN BERTHI ROAD of £73,000 on 29th May 2013. For the value to have increased from £73,000 to £142,214 over the eleven years and eleven months to June 2025, the following assumptions must hold true:
