CWRT COLLEN Price Paid vs. HPI Average

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 CWRT COLLEN sales from September 1998 and December 2007 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 1998 sale was for 75% above the HPI. So the extrapolation line tracks at 75% above the HPI over time, until the December 2007 sale, where it falls to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might CWRT COLLEN be worth now?

This is based on house price inflation of 65.4%, between December 2007 and February 2025, 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 65.4% inflationary increase is applied to the most recent sale price for CWRT COLLEN of £497,500 on 3rd December 2007. For the value to have increased from £497,500 to £822,764 over the eighteen years and ten months to February 2025, the following assumptions must hold true:
