15 PLAS TALIESIN 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 15 PLAS TALIESIN sales from June 2002 and July 2011 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 June 2002 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the July 2011 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 15 PLAS TALIESIN be worth now?

15 PLAS TALIESIN might now be worth an estimated £602,873.

This is based on house price inflation of 77.3%, between July 2011 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 77.3% inflationary increase is applied to the most recent sale price for 15 PLAS TALIESIN of £340,000 on 29th July 2011. For the value to have increased from £340,000 to £602,873 over the twelve years and seven months to December 2024, the following assumptions must hold true:

• The value of 15 PLAS TALIESIN has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The July 2011 sale price of £340,000 represented a fair market value for the property.
