11 MARINE PARADE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The four 11 MARINE PARADE sales between May 2005 and June 2023 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 October 2021 sale was for 379% above the HPI. So the extrapolation line tracks at 379% above the HPI over time, until the June 2023 sale, where it rises to 492% above the HPI. The line then continues to track at 492% above the HPI.

What might 11 MARINE PARADE be worth now?

This is based on house price inflation of 2.4%, between June 2023 and December 2024, for 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 2.4% inflationary increase is applied to the most recent sale price for 11 MARINE PARADE of £2,950,000 on 2nd June 2023. For the value to have increased from £2,950,000 to £3,021,256 over the six months to December 2024, the following assumptions must hold true:

• The value of 11 MARINE PARADE has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The June 2023 sale price of £2,950,000 represented a fair market value for the property.
