21 CLOS GWY Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The five 21 CLOS GWY sales between February 1995 and April 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 December 2020 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the April 2024 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 21 CLOS GWY be worth now?

21 CLOS GWY might now be worth an estimated £228,081.

This is based on house price inflation of 3.9%, between April 2024 and June 2025, for terraced 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 3.9% inflationary increase is applied to the most recent sale price for 21 CLOS GWY of £219,500 on 19th April 2024. For the value to have increased from £219,500 to £228,081 over the ten months to June 2025, the following assumptions must hold true:

• The value of 21 CLOS GWY has moved in line with the HPI for terraced houses in the Cardiff local authority area.
• The April 2024 sale price of £219,500 represented a fair market value for the property.
• The size, condition, and specification of 21 CLOS GWY has not materially changed since April 2024.
