9 CLOS ISLWYN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 9 CLOS ISLWYN sales from August 2000 and October 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 August 2000 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the October 2010 sale, where it falls to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 9 CLOS ISLWYN be worth now?

9 CLOS ISLWYN might now be worth an estimated £364,982.

This is based on house price inflation of 58%, between October 2010 and December 2024, for detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 58% inflationary increase is applied to the most recent sale price for 9 CLOS ISLWYN of £231,000 on 1st October 2010. For the value to have increased from £231,000 to £364,982 over the thirteen years and ten months to December 2024, the following assumptions must hold true:

• The value of 9 CLOS ISLWYN has moved in line with the HPI for detached houses in the Swansea local authority area.
• The October 2010 sale price of £231,000 represented a fair market value for the property.
