12 HEOL DOLWEN 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 two 12 HEOL DOLWEN sales from March 2003 and March 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 March 2003 sale was for 65% above the HPI. So the extrapolation line tracks at 65% above the HPI over time, until the March 2020 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 12 HEOL DOLWEN be worth now?

12 HEOL DOLWEN might now be worth an estimated £439,081.

This is based on house price inflation of 32.1%, between March 2020 and February 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 32.1% inflationary increase is applied to the most recent sale price for 12 HEOL DOLWEN of £332,500 on 6th March 2020. For the value to have increased from £332,500 to £439,081 over the five years and one month to February 2025, the following assumptions must hold true:

  • The value of 12 HEOL DOLWEN has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
  • The March 2020 sale price of £332,500 represented a fair market value for the property.
  • The size, condition, and specification of 12 HEOL DOLWEN has not materially changed since March 2020.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
