The below table shows the price paid for the two sales, along with the average semi-detached price in the Vale of Glamorgan local authority area for the corresponding sale date.

| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

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 two 21 RHODFA SWELDON sales from March 1999 and December 2004 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 March 1999 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the December 2004 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

21 RHODFA SWELDON might now be worth an estimated £259,361.
This is based on house price inflation of 92.1%, between December 2004 and April 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 92.1% inflationary increase is applied to the most recent sale price for 21 RHODFA SWELDON of £135,000 on 3rd December 2004. For the value to have increased from £135,000 to £259,361 over the 22 years and eight months to April 2026, the following assumptions must hold true:
