The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The four 21 HEOL Y CAE sales between November 1999 and September 2021 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 December 2018 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the September 2021 sale, where it rises to 31% below the HPI. The line then continues to track at 31% below the HPI.
21 HEOL Y CAE might now be worth an estimated £146,848.
This is based on house price inflation of 22.4%, between September 2021 and June 2025, for semi-detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 22.4% inflationary increase is applied to the most recent sale price for 21 HEOL Y CAE of £120,000 on 29th September 2021. For the value to have increased from £120,000 to £146,848 over the four years and three months to June 2025, the following assumptions must hold true:
