The below graph shows the average semi-detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The three 80 PENYWERN ROAD sales between May 1996 and October 2023 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 1997 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the October 2023 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.
80 PENYWERN ROAD might now be worth an estimated £84,355.
This is based on house price inflation of 5.4%, between October 2023 and February 2025, for semi-detached houses, in the Neath Port Talbot local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.4% inflationary increase is applied to the most recent sale price for 80 PENYWERN ROAD of £80,000 on 13th October 2023. For the value to have increased from £80,000 to £84,355 over the two years and eight months to February 2025, the following assumptions must hold true:
