6 CWM ALARCH 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 four 6 CWM ALARCH sales between July 1998 and April 2016 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 2010 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the April 2016 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 6 CWM ALARCH be worth now?

6 CWM ALARCH might now be worth an estimated £200,080.

This is based on house price inflation of 60.1%, between April 2016 and February 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 60.1% inflationary increase is applied to the most recent sale price for 6 CWM ALARCH of £125,000 on 19th April 2016. For the value to have increased from £125,000 to £200,080 over the nine years and two months to February 2025, the following assumptions must hold true:

• The value of 6 CWM ALARCH has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The April 2016 sale price of £125,000 represented a fair market value for the property.
• The size, condition, and specification of 6 CWM ALARCH has not materially changed since April 2016.
