1 CASTLE RISE 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 two 1 CASTLE RISE sales from February 2004 and October 2015 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 February 2004 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the October 2015 sale, where it falls to 35% below the HPI. The line then continues to track at 35% below the HPI.

What might 1 CASTLE RISE be worth now?

1 CASTLE RISE might now be worth an estimated £338,961.

This is based on house price inflation of 50.6%, between October 2015 and December 2024, 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 50.6% inflationary increase is applied to the most recent sale price for 1 CASTLE RISE of £225,000 on 29th October 2015. For the value to have increased from £225,000 to £338,961 over the eight years and ten months to December 2024, the following assumptions must hold true:

• The value of 1 CASTLE RISE has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The October 2015 sale price of £225,000 represented a fair market value for the property.
• The size, condition, and specification of 1 CASTLE RISE has not materially changed since October 2015.
