8 TAIR GWAUN 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 8 TAIR GWAUN sales from December 2004 and July 2015 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 December 2004 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the July 2015 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 8 TAIR GWAUN be worth now?

8 TAIR GWAUN might now be worth an estimated £608,586.

This is based on house price inflation of 54.1%, between July 2015 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 54.1% inflationary increase is applied to the most recent sale price for 8 TAIR GWAUN of £395,000 on 21st July 2015. For the value to have increased from £395,000 to £608,586 over the eight years and seven months to December 2024, the following assumptions must hold true:

• The value of 8 TAIR GWAUN has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The July 2015 sale price of £395,000 represented a fair market value for the property.
