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 six 20 CLOS OGNEY sales between October 1996 and October 2017 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 2015 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the October 2017 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

20 CLOS OGNEY might now be worth an estimated £299,180.
This is based on house price inflation of 42.5%, between October 2017 and May 2026, 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 42.5% inflationary increase is applied to the most recent sale price for 20 CLOS OGNEY of £210,000 on 6th October 2017. For the value to have increased from £210,000 to £299,180 over the nine years and five months to May 2026, the following assumptions must hold true:
