13 HEOL ISAF Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 13 HEOL ISAF sales between April 2010 and October 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 September 2013 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the October 2021 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might 13 HEOL ISAF be worth now?

13 HEOL ISAF might now be worth an estimated £396,534.

This is based on house price inflation of 14.9%, between October 2021 and June 2025, for semi-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 14.9% inflationary increase is applied to the most recent sale price for 13 HEOL ISAF of £345,000 on 22nd October 2021. For the value to have increased from £345,000 to £396,534 over the four years and four months to June 2025, the following assumptions must hold true:

• The value of 13 HEOL ISAF has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
• The October 2021 sale price of £345,000 represented a fair market value for the property.
• The size, condition, and specification of 13 HEOL ISAF has not materially changed since October 2021.
