Land registry data shows two sales for 5 CLAS ISAN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Cardiff local authority area for the corresponding sale date.

The average price is sourced from the Office for National Statistics' House Price Index (HPI).

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 5 CLAS ISAN sales from September 2013 and January 2020 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 2013 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the January 2020 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.
5 CLAS ISAN might now be worth an estimated £593,076.
This is based on house price inflation of 26.2%, between January 2020 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 26.2% inflationary increase is applied to the most recent sale price for 5 CLAS ISAN of £470,000 on 6th January 2020. For the value to have increased from £470,000 to £593,076 over the four years and seven months to June 2025, the following assumptions must hold true:
