7 LLYS DERWEN 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 7 LLYS DERWEN sales between June 1998 and September 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 May 2011 sale was for 103% above the HPI. So the extrapolation line tracks at 103% above the HPI over time, until the September 2021 sale, where it falls to 101% above the HPI. The line then continues to track at 101% above the HPI.

What might 7 LLYS DERWEN be worth now?

7 LLYS DERWEN might now be worth an estimated £558,444.

This is based on house price inflation of 22.7%, between September 2021 and December 2024, 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 22.7% inflationary increase is applied to the most recent sale price for 7 LLYS DERWEN of £455,000 on 13th September 2021. For the value to have increased from £455,000 to £558,444 over the two years and nine months to December 2024, the following assumptions must hold true:

• The value of 7 LLYS DERWEN has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The September 2021 sale price of £455,000 represented a fair market value for the property.
