The below graph shows the average terraced house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 21 PLASSEY SQUARE sales from January 2019 and January 2020 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 January 2019 sale was for 55% above the HPI. So the extrapolation line tracks at 55% above the HPI over time, until the January 2020 sale, where it rises to 145% above the HPI. The line then continues to track at 145% above the HPI.

21 PLASSEY SQUARE might now be worth an estimated £585,435.
This is based on house price inflation of 34.6%, between January 2020 and May 2026, for terraced 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 34.6% inflationary increase is applied to the most recent sale price for 21 PLASSEY SQUARE of £435,000 on 31st January 2020. For the value to have increased from £435,000 to £585,435 over the five years and eight months to May 2026, the following assumptions must hold true:
