The below graph shows the average terraced house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The three 137 BONVILSTON ROAD sales between July 1996 and May 2011 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 August 2003 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the May 2011 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

137 BONVILSTON ROAD might now be worth an estimated £121,461.
This is based on house price inflation of 95.9%, between May 2011 and July 2025, for terraced 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 95.9% inflationary increase is applied to the most recent sale price for 137 BONVILSTON ROAD of £62,000 on 17th May 2011. For the value to have increased from £62,000 to £121,461 over the thirteen years and ten months to July 2025, the following assumptions must hold true:
