20 HEOL SERTH 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 20 HEOL SERTH sales from November 2015 and September 2021 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 November 2015 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the September 2021 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might 20 HEOL SERTH be worth now?

This is based on house price inflation of 24.1%, between September 2021 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 24.1% inflationary increase is applied to the most recent sale price for 20 HEOL SERTH of £336,000 on 24th September 2021. For the value to have increased from £336,000 to £416,929 over the four years and seven months to February 2025, the following assumptions must hold true:

• The value of 20 HEOL SERTH has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The September 2021 sale price of £336,000 represented a fair market value for the property.
