10 TANYBRYN 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 10 TANYBRYN sales from September 2015 and November 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 September 2015 sale was for 52% below the HPI. So the extrapolation line tracks at 52% below the HPI over time, until the November 2018 sale, where it rises to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 10 TANYBRYN be worth now?

10 TANYBRYN might now be worth an estimated £177,263.

This is based on house price inflation of 41.8%, between November 2018 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 41.8% inflationary increase is applied to the most recent sale price for 10 TANYBRYN of £125,000 on 5th November 2018. For the value to have increased from £125,000 to £177,263 over the seven years and nine months to February 2025, the following assumptions must hold true:

• The value of 10 TANYBRYN has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The November 2018 sale price of £125,000 represented a fair market value for the property.
