18 HEOL GWRGAN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 18 HEOL GWRGAN sales between July 2016 and October 2020 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 April 2019 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the October 2020 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 18 HEOL GWRGAN be worth now?

This is based on house price inflation of 24.6%, between October 2020 and December 2024, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 24.6% inflationary increase is applied to the most recent sale price for 18 HEOL GWRGAN of £315,000 on 6th October 2020. For the value to have increased from £315,000 to £392,466 over the three years and ten months to December 2024, the following assumptions must hold true:

• The October 2020 sale price of £315,000 represented a fair market value for the property.
