The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The three 121 PEN Y CAE sales between February 2000 and May 2020 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 2005 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the May 2020 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

121 PEN Y CAE might now be worth an estimated £165,283.
This is based on house price inflation of 50.3%, between May 2020 and April 2026, 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 50.3% inflationary increase is applied to the most recent sale price for 121 PEN Y CAE of £110,000 on 22nd May 2020. For the value to have increased from £110,000 to £165,283 over the six years and one month to April 2026, the following assumptions must hold true:
