The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The four 11 TWYNYFFALD ROAD sales between December 1995 and June 2019 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 March 2015 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the June 2019 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.

11 TWYNYFFALD ROAD might now be worth an estimated £179,363.
This is based on house price inflation of 43.5%, between June 2019 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 43.5% inflationary increase is applied to the most recent sale price for 11 TWYNYFFALD ROAD of £125,000 on 10th June 2019. For the value to have increased from £125,000 to £179,363 over the five years and eleven months to July 2025, the following assumptions must hold true:
