9 CAE GWYN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 9 CAE GWYN sales from September 2005 and October 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 2005 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the October 2025 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 9 CAE GWYN be worth now?

9 CAE GWYN might now be worth an estimated £254,684.

This is based on house price deflation of 2%, between October 2025 and May 2026, for semi-detached 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 2% deflationary decrease is applied to the most recent sale price for 9 CAE GWYN of £260,000 on 24th October 2025. For the value to have decreased from £260,000 to £254,684 over the one year and five months to May 2026, the following assumptions must hold true:

• The value of 9 CAE GWYN has moved in line with the HPI for semi-detached houses in the Vale of Glamorgan local authority area.
• The October 2025 sale price of £260,000 represented a fair market value for the property.
• The size, condition, and specification of 9 CAE GWYN has not materially changed since October 2025.
