18 HEOL YR ONNEN 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 18 HEOL YR ONNEN sales between July 1997 and August 2011 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 August 2005 sale was for 32% above the HPI. So the extrapolation line tracks at 32% above the HPI over time, until the August 2011 sale, which was also at 32% above the HPI.

What might 18 HEOL YR ONNEN be worth now?

18 HEOL YR ONNEN might now be worth an estimated £370,152.

This is based on house price inflation of 94.8%, between August 2011 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 94.8% inflationary increase is applied to the most recent sale price for 18 HEOL YR ONNEN of £190,000 on 25th August 2011. For the value to have increased from £190,000 to £370,152 over the fourteen years and two months to June 2025, the following assumptions must hold true:

• The value of 18 HEOL YR ONNEN has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The August 2011 sale price of £190,000 represented a fair market value for the property.
