The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 16 HEOL NANT CASTAN sales between November 1998 and August 2014 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 April 2006 sale was for 26% above the HPI. So the extrapolation line tracks at 26% above the HPI over time, until the August 2014 sale, which was also at 26% above the HPI.
16 HEOL NANT CASTAN might now be worth an estimated £399,597.
This is based on house price inflation of 62.4%, between August 2014 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 62.4% inflationary increase is applied to the most recent sale price for 16 HEOL NANT CASTAN of £246,000 on 1st August 2014. For the value to have increased from £246,000 to £399,597 over the eleven years and two months to June 2025, the following assumptions must hold true:
