The below graph shows the average terraced house price in the Bridgend local authority area over time, sourced from the HPI. The two 21 BLACKMILL ROAD sales from June 2012 and September 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 June 2012 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the September 2017 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.
21 BLACKMILL ROAD might now be worth an estimated £205,193.
This is based on house price inflation of 53.1%, between September 2017 and June 2025, for terraced houses, in the Bridgend local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 53.1% inflationary increase is applied to the most recent sale price for 21 BLACKMILL ROAD of £134,000 on 11th September 2017. For the value to have increased from £134,000 to £205,193 over the eight years and three months to June 2025, the following assumptions must hold true:
