9 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 9 TANYBRYN sales from November 2012 and August 2021 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 2012 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the August 2021 sale, where it falls to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 9 TANYBRYN be worth now?

9 TANYBRYN might now be worth an estimated £183,607.

This is based on house price inflation of 14.8%, between August 2021 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 14.8% inflationary increase is applied to the most recent sale price for 9 TANYBRYN of £160,000 on 9th August 2021. For the value to have increased from £160,000 to £183,607 over the four years and six months to February 2025, the following assumptions must hold true:

• The value of 9 TANYBRYN has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The August 2021 sale price of £160,000 represented a fair market value for the property.
