The below graph shows the average detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The four 25 HEOL YR ONNEN sales between September 1998 and February 2010 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 October 2003 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the February 2010 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.
25 HEOL YR ONNEN might now be worth an estimated £313,431.
This is based on house price inflation of 97.7%, between February 2010 and June 2025, for detached houses, in the Rhondda Cynon Taf local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 97.7% inflationary increase is applied to the most recent sale price for 25 HEOL YR ONNEN of £158,500 on 8th February 2010. For the value to have increased from £158,500 to £313,431 over the fourteen years and eight months to June 2025, the following assumptions must hold true:
