25 CLOS Y CARLWM Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 25 CLOS Y CARLWM sales between October 1997 and November 1999 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 September 1999 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the November 1999 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 25 CLOS Y CARLWM be worth now?

This is based on house price inflation of 348.7%, between November 1999 and June 2025, for semi-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 348.7% inflationary increase is applied to the most recent sale price for 25 CLOS Y CARLWM of £56,500 on 1st November 1999. For the value to have increased from £56,500 to £253,520 over the 26 years and five months to June 2025, the following assumptions must hold true:
