16 TAI DYFFRYN 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 two 16 TAI DYFFRYN sales from January 2016 and April 2018 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 January 2016 sale was for 144% above the HPI. So the extrapolation line tracks at 144% above the HPI over time, until the April 2018 sale, where it rises to 153% above the HPI. The line then continues to track at 153% above the HPI.

What might 16 TAI DYFFRYN be worth now?

16 TAI DYFFRYN might now be worth an estimated £712,584.

This is based on house price inflation of 65.7%, between April 2018 and June 2025, for 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 65.7% inflationary increase is applied to the most recent sale price for 16 TAI DYFFRYN of £430,000 on 24th April 2018. For the value to have increased from £430,000 to £712,584 over the six years and ten months to June 2025, the following assumptions must hold true:

  • The value of 16 TAI DYFFRYN has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
  • The April 2018 sale price of £430,000 represented a fair market value for the property.
  • The size, condition, and specification of 16 TAI DYFFRYN has not materially changed since April 2018.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
