The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The five 20 PLYNLIMON AVENUE sales between December 2003 and October 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 October 2018 sale was for 26% above the HPI. So the extrapolation line tracks at 26% above the HPI over time, until the October 2021 sale, which was also at 26% above the HPI.

20 PLYNLIMON AVENUE might now be worth an estimated £204,130.
This is based on house price inflation of 20.1%, between October 2021 and July 2025, for terraced houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 20.1% inflationary increase is applied to the most recent sale price for 20 PLYNLIMON AVENUE of £170,000 on 15th October 2021. For the value to have increased from £170,000 to £204,130 over the four years and three months to July 2025, the following assumptions must hold true:
