15 TREM YR EFAIL Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The two 15 TREM YR EFAIL sales from July 2001 and April 2024 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 July 2001 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the April 2024 sale, where it falls to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 15 TREM YR EFAIL be worth now?

15 TREM YR EFAIL might now be worth an estimated £176,235.

This is based on house price inflation of 6.8%, between April 2024 and July 2025, for terraced 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 6.8% inflationary increase is applied to the most recent sale price for 15 TREM YR EFAIL of £165,000 on 23rd April 2024. For the value to have increased from £165,000 to £176,235 over the nine months to July 2025, the following assumptions must hold true:

• The value of 15 TREM YR EFAIL has moved in line with the HPI for terraced houses in the Caerphilly local authority area.
• The April 2024 sale price of £165,000 represented a fair market value for the property.
