The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 4 CLOS YR EOS sales between June 1996 and August 2005 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 July 2001 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the August 2005 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.

4 CLOS YR EOS might now be worth an estimated £714,281.
This is based on house price inflation of 88%, between August 2005 and May 2026, 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 88% inflationary increase is applied to the most recent sale price for 4 CLOS YR EOS of £380,000 on 30th August 2005. For the value to have increased from £380,000 to £714,281 over the 21 years and three months to May 2026, the following assumptions must hold true:
