23 BRON Y DERI Price Paid vs. HPI Average

The below graph shows the average detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The three 23 BRON Y DERI sales between April 2000 and January 2014 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 November 2007 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the January 2014 sale, where it rises to 27% above the HPI. The line then continues to track at 27% above the HPI.

What might 23 BRON Y DERI be worth now?

The 82.9% inflationary increase is applied to the most recent sale price for 23 BRON Y DERI of £185,000 on 10th January 2014. For the value to have increased from £185,000 to £338,331 over the ten years and eleven months to February 2025, the following assumptions must hold true:
