12 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 two 12 CLOS ONNEN sales from June 2001 and June 2002 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 2001 sale was for 91% above the HPI. So the extrapolation line tracks at 91% above the HPI over time, until the June 2002 sale, where it falls to 86% above the HPI. The line then continues to track at 86% above the HPI.

What might 12 CLOS ONNEN be worth now?

12 CLOS ONNEN might now be worth an estimated £466,157.

This is based on house price inflation of 246.6%, between June 2002 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 246.6% inflationary increase is applied to the most recent sale price for 12 CLOS ONNEN of £134,500 on 27th June 2002. For the value to have increased from £134,500 to £466,157 over the 23 years and four months to February 2025, the following assumptions must hold true:

• The value of 12 CLOS ONNEN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The June 2002 sale price of £134,500 represented a fair market value for the property.
