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?

This is based on house price inflation of 41.6%, between July 2019 and March 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 41.6% 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 £334,605 over the six years and four months to March 2025, the following assumptions must hold true:
