TALIESIN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two TALIESIN sales from June 2004 and November 2014 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 2004 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the November 2014 sale, where it rises to 154% above the HPI. The line then continues to track at 154% above the HPI.

What might TALIESIN be worth now?

TALIESIN might now be worth an estimated £788,320.

This is based on house price inflation of 79.2%, between November 2014 and February 2025, for detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 79.2% inflationary increase is applied to the most recent sale price for TALIESIN of £440,000 on 7th November 2014. For the value to have increased from £440,000 to £788,320 over the eleven years and nine months to February 2025, the following assumptions must hold true:

• The value of TALIESIN has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The November 2014 sale price of £440,000 represented a fair market value for the property.
• The size, condition, and specification of TALIESIN has not materially changed since November 2014.
