The below graph shows the average terraced house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The five 21 CAE GWYN sales between October 2005 and May 2025 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 September 2021 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the May 2025 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.
21 CAE GWYN might now be worth an estimated £265,841.
This is based on house price inflation of 0.3%, between May 2025 and June 2025, for terraced houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 0.3% inflationary increase is applied to the most recent sale price for 21 CAE GWYN of £265,000 on 21st May 2025. For the value to have increased from £265,000 to £265,841 over the eleven months to June 2025, the following assumptions must hold true:
