| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2014 27 JAN | £372,500 | £308,151 | 21% above HPI |
2009 25 SEP | £360,000 | £284,083 | 27% above HPI |
The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 56 COG ROAD sales from September 2009 and January 2014 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 September 2009 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the January 2014 sale, where it falls to 21% above the HPI. The line then continues to track at 21% above the HPI.

56 COG ROAD might now be worth an estimated £628,868.
This is based on house price inflation of 68.8%, between January 2014 and April 2026, for 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 68.8% inflationary increase is applied to the most recent sale price for 56 COG ROAD of £372,500 on 27th January 2014. For the value to have increased from £372,500 to £628,868 over the eleven years and nine months to April 2026, the following assumptions must hold true:
