7 HEOL CEFN ONN 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 7 HEOL CEFN ONN sales from October 2011 and July 2023 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 October 2011 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the July 2023 sale, where it rises to 52% above the HPI. The line then continues to track at 52% above the HPI.

What might 7 HEOL CEFN ONN be worth now?

This is based on house price inflation of 4.5%, between July 2023 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 4.5% inflationary increase is applied to the most recent sale price for 7 HEOL CEFN ONN of £760,000 on 3rd July 2023. For the value to have increased from £760,000 to £794,304 over the two years and five months to February 2025, the following assumptions must hold true:
