145 HEOL ISAF 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 two 145 HEOL ISAF sales from July 2009 and August 2019 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 2009 sale was for 152% above the HPI. So the extrapolation line tracks at 152% above the HPI over time, until the August 2019 sale, where it falls to 132% above the HPI. The line then continues to track at 132% above the HPI.

What might 145 HEOL ISAF be worth now?

145 HEOL ISAF might now be worth an estimated £1,210,621.

This is based on house price inflation of 29.5%, between August 2019 and February 2025, 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 29.5% inflationary increase is applied to the most recent sale price for 145 HEOL ISAF of £935,000 on 29th August 2019. For the value to have increased from £935,000 to £1,210,621 over the six years and six months to February 2025, the following assumptions must hold true:

• The value of 145 HEOL ISAF has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The August 2019 sale price of £935,000 represented a fair market value for the property.
