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 four 40 LLYS DWYNWEN sales between March 1997 and June 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 June 2005 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the June 2007 sale, where it falls to 21% below the HPI. The line then continues to track at 21% below the HPI.
40 LLYS DWYNWEN might now be worth an estimated £237,736.
This is based on house price inflation of 71.7%, between June 2007 and February 2025, 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 71.7% inflationary increase is applied to the most recent sale price for 40 LLYS DWYNWEN of £138,500 on 22nd June 2007. For the value to have increased from £138,500 to £237,736 over the eighteen years and four months to February 2025, the following assumptions must hold true:
