RED GABLES 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 two RED GABLES sales from November 1996 and August 2009 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 November 1996 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the August 2009 sale, where it rises to 47% above the HPI. The line then continues to track at 47% above the HPI.

What might RED GABLES be worth now?

RED GABLES might now be worth an estimated £747,318.

This is based on house price inflation of 84.5%, between August 2009 and June 2025, 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 84.5% inflationary increase is applied to the most recent sale price for RED GABLES of £405,000 on 14th August 2009. For the value to have increased from £405,000 to £747,318 over the sixteen years and two months to June 2025, the following assumptions must hold true:

• The value of RED GABLES has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The August 2009 sale price of £405,000 represented a fair market value for the property.
• The size, condition, and specification of RED GABLES has not materially changed since August 2009.
