The below graph shows the average terraced house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The five 23 CLOS ONNEN sales between April 2000 and March 2019 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 March 2017 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the March 2019 sale, where it rises to 71% above the HPI. The line then continues to track at 71% above the HPI.
23 CLOS ONNEN might now be worth an estimated £231,216.
This is based on house price inflation of 59.5%, between March 2019 and June 2025, 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 59.5% inflationary increase is applied to the most recent sale price for 23 CLOS ONNEN of £145,000 on 29th March 2019. For the value to have increased from £145,000 to £231,216 over the five years and nine months to June 2025, the following assumptions must hold true:
