1 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 1 CLOS ONNEN sales between June 2000 and November 2018 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 April 2017 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the November 2018 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 1 CLOS ONNEN be worth now?

1 CLOS ONNEN might now be worth an estimated £355,654.

This is based on house price inflation of 43.7%, between November 2018 and December 2024, 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 43.7% inflationary increase is applied to the most recent sale price for 1 CLOS ONNEN of £247,500 on 20th November 2018. For the value to have increased from £247,500 to £355,654 over the five years and eleven months to December 2024, the following assumptions must hold true:

• The value of 1 CLOS ONNEN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The November 2018 sale price of £247,500 represented a fair market value for the property.
• The size, condition, and specification of 1 CLOS ONNEN has not materially changed since November 2018.
