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 23 OLD MILL ROAD sales from July 2002 and December 2002 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 2002 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the December 2002 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.

23 OLD MILL ROAD might now be worth an estimated £225,787.

The 199.1% inflationary increase is applied to the most recent sale price for 23 OLD MILL ROAD of £75,500 on 10th December 2002. For the value to have increased from £75,500 to £225,787 over the 24 years and seven months to May 2026, the following assumptions must hold true:
