The below graph shows the average terraced house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The two 17 HILLSIDE sales from June 2006 and September 2025 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 2006 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the September 2025 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

17 HILLSIDE might now be worth an estimated £152,598.
This is based on house price inflation of 0.4%, between September 2025 and May 2026, for terraced 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 0.4% inflationary increase is applied to the most recent sale price for 17 HILLSIDE of £152,000 on 12th September 2025. For the value to have increased from £152,000 to £152,598 over the one year and four months to May 2026, the following assumptions must hold true:
