28 CLOS ONNEN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The two 28 CLOS ONNEN sales from May 2000 and December 2010 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 May 2000 sale was for 59% above the HPI. So the extrapolation line tracks at 59% above the HPI over time, until the December 2010 sale, where it falls to 33% above the HPI. The line then continues to track at 33% above the HPI.

What might 28 CLOS ONNEN be worth now?

28 CLOS ONNEN might now be worth an estimated £213,615.

This is based on house price inflation of 76.5%, between December 2010 and February 2025, for semi-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 76.5% inflationary increase is applied to the most recent sale price for 28 CLOS ONNEN of £121,000 on 22nd December 2010. For the value to have increased from £121,000 to £213,615 over the fifteen years and ten months to February 2025, the following assumptions must hold true:

• The value of 28 CLOS ONNEN has moved in line with the HPI for semi-detached houses in the Neath Port Talbot local authority area.
• The December 2010 sale price of £121,000 represented a fair market value for the property.
