10 CLOS ONNEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The three 10 CLOS ONNEN sales between July 2001 and July 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 February 2019 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the July 2019 sale, where it rises to 36% above the HPI. The line then continues to track at 36% above the HPI.

What might 10 CLOS ONNEN be worth now?

10 CLOS ONNEN might now be worth an estimated £338,986.

This is based on house price inflation of 43.5%, between July 2019 and February 2025, for 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 43.5% inflationary increase is applied to the most recent sale price for 10 CLOS ONNEN of £236,250 on 12th July 2019. For the value to have increased from £236,250 to £338,986 over the six years and five months to February 2025, the following assumptions must hold true:

  • The value of 10 CLOS ONNEN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
  • The July 2019 sale price of £236,250 represented a fair market value for the property.
  • The size, condition, and specification of 10 CLOS ONNEN has not materially changed since July 2019.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
