14 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 three 14 CLOS ISLWYN sales between October 1999 and November 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 October 2005 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the November 2019 sale, which was also at 15% above the HPI.

What might 14 CLOS ISLWYN be worth now?

14 CLOS ISLWYN might now be worth an estimated £370,056.

This is based on house price inflation of 32.2%, between November 2019 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 32.2% inflationary increase is applied to the most recent sale price for 14 CLOS ISLWYN of £280,000 on 7th November 2019. For the value to have increased from £280,000 to £370,056 over the four years and eleven months to December 2024, the following assumptions must hold true:

• The value of 14 CLOS ISLWYN has moved in line with the HPI for detached houses in the Swansea local authority area.
• The November 2019 sale price of £280,000 represented a fair market value for the property.
• The size, condition, and specification of 14 CLOS ISLWYN has not materially changed since November 2019.
