The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The four 10 RHOS Y DDERWEN sales between March 2001 and July 2022 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 2013 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the July 2022 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.
10 RHOS Y DDERWEN might now be worth an estimated £313,446.
This is based on house price inflation of 10%, between July 2022 and December 2024, for 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 10% inflationary increase is applied to the most recent sale price for 10 RHOS Y DDERWEN of £284,950 on 12th July 2022. For the value to have increased from £284,950 to £313,446 over the one year and seven months to December 2024, the following assumptions must hold true:
