The below graph shows the average semi-detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The four 30 HEOL COLLEN sales between April 1995 and November 2006 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 May 2004 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the November 2006 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.
30 HEOL COLLEN might now be worth an estimated £299,185.
This is based on house price inflation of 78.1%, between November 2006 and June 2025, for semi-detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 78.1% inflationary increase is applied to the most recent sale price for 30 HEOL COLLEN of £168,000 on 27th November 2006. For the value to have increased from £168,000 to £299,185 over the nineteen years and five months to June 2025, the following assumptions must hold true:
