| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three 11 NEWFOUNDLAND WAY sales between March 1996 and May 2011 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 2008 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the May 2011 sale, where it rises to 39% above the HPI. The line then continues to track at 39% above the HPI.

11 NEWFOUNDLAND WAY might now be worth an estimated £269,006.
This is based on house price inflation of 88.8%, between May 2011 and July 2025, for semi-detached 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 88.8% inflationary increase is applied to the most recent sale price for 11 NEWFOUNDLAND WAY of £142,500 on 23rd May 2011. For the value to have increased from £142,500 to £269,006 over the thirteen years and ten months to July 2025, the following assumptions must hold true:
