TEGFAN 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 TEGFAN sales from June 1997 and October 2023 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 1997 sale was for 155% above the HPI. So the extrapolation line tracks at 155% above the HPI over time, until the October 2023 sale, where it falls to 67% above the HPI. The line then continues to track at 67% above the HPI.

What might TEGFAN be worth now?

TEGFAN might now be worth an estimated £519,887.

This is based on house price inflation of 6.1%, between October 2023 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 6.1% inflationary increase is applied to the most recent sale price for TEGFAN of £490,000 on 20th October 2023. For the value to have increased from £490,000 to £519,887 over the two years and eight months to February 2025, the following assumptions must hold true:

• The value of TEGFAN has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The October 2023 sale price of £490,000 represented a fair market value for the property.
• The size, condition, and specification of TEGFAN has not materially changed since October 2023.
