1 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 1 TAIR GWAUN sales from December 2003 and March 2010 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 2003 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the March 2010 sale, where it falls to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 1 TAIR GWAUN be worth now?

1 TAIR GWAUN might now be worth an estimated £703,512.

This is based on house price inflation of 78.1%, between March 2010 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 78.1% inflationary increase is applied to the most recent sale price for 1 TAIR GWAUN of £395,000 on 12th March 2010. For the value to have increased from £395,000 to £703,512 over the thirteen years and three months to December 2024, the following assumptions must hold true:

• The value of 1 TAIR GWAUN has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The March 2010 sale price of £395,000 represented a fair market value for the property.
• The size, condition, and specification of 1 TAIR GWAUN has not materially changed since March 2010.
