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 100 ROBERT STREET sales between December 2006 and October 2021 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 2010 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the October 2021 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.

100 ROBERT STREET might now be worth an estimated £146,968.
This is based on house price inflation of 27.8%, between October 2021 and May 2026, 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 27.8% inflationary increase is applied to the most recent sale price for 100 ROBERT STREET of £115,000 on 8th October 2021. For the value to have increased from £115,000 to £146,968 over the five years and five months to May 2026, the following assumptions must hold true:
