4 CLOS GWY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 4 CLOS GWY sales between November 2012 and October 2024 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 July 2020 sale was for 34% below the HPI. So the extrapolation line tracks at 34% below the HPI over time, until the October 2024 sale, which was also at 34% below the HPI.

What might 4 CLOS GWY be worth now?

4 CLOS GWY might now be worth an estimated £340,398.

This is based on house price inflation of 1.6%, between October 2024 and June 2025, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.6% inflationary increase is applied to the most recent sale price for 4 CLOS GWY of £335,000 on 25th October 2024. For the value to have increased from £335,000 to £340,398 over the one year and four months to June 2025, the following assumptions must hold true:

• The value of 4 CLOS GWY has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The October 2024 sale price of £335,000 represented a fair market value for the property.
• The size, condition, and specification of 4 CLOS GWY has not materially changed since October 2024.
