The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 9 COED MAWR sales from May 1998 and October 2001 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 May 1998 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the October 2001 sale, where it falls to 35% above the HPI. The line then continues to track at 35% above the HPI.
9 COED MAWR might now be worth an estimated £264,637.
This is based on house price inflation of 316.4%, between October 2001 and December 2024, for semi-detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 316.4% inflationary increase is applied to the most recent sale price for 9 COED MAWR of £63,550 on 12th October 2001. For the value to have increased from £63,550 to £264,637 over the 22 years and ten months to December 2024, the following assumptions must hold true:
