The below graph shows the average terraced house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 20 ROBERT STREET sales from July 2004 and May 2024 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 July 2004 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the May 2024 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

20 ROBERT STREET might now be worth an estimated £137,166.
This is based on house price inflation of 14.3%, between May 2024 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 14.3% inflationary increase is applied to the most recent sale price for 20 ROBERT STREET of £120,000 on 29th May 2024. For the value to have increased from £120,000 to £137,166 over the two years to May 2026, the following assumptions must hold true:
