The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The five 15 KELVIN ROAD sales between December 2001 and May 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 January 2015 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the May 2021 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.
15 KELVIN ROAD might now be worth an estimated £154,071.
This is based on house price inflation of 23.3%, between May 2021 and December 2024, 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 23.3% inflationary increase is applied to the most recent sale price for 15 KELVIN ROAD of £125,000 on 19th May 2021. For the value to have increased from £125,000 to £154,071 over the two years and five months to December 2024, the following assumptions must hold true:
