5 BRON Y DERI Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 5 BRON Y DERI sales from October 1998 and September 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 October 1998 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the September 2024 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 5 BRON Y DERI be worth now?

5 BRON Y DERI might now be worth an estimated £142,153.

This is based on house price inflation of 11.9%, between September 2024 and May 2026, for semi-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 11.9% inflationary increase is applied to the most recent sale price for 5 BRON Y DERI of £127,000 on 27th September 2024. For the value to have increased from £127,000 to £142,153 over the two years and four months to May 2026, the following assumptions must hold true:

• The value of 5 BRON Y DERI has moved in line with the HPI for semi-detached houses in the Rhondda Cynon Taf local authority area.
