The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 19 BLAEN IFOR sales from December 2000 and April 2002 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 December 2000 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the April 2002 sale, where it rises to 34% above the HPI. The line then continues to track at 34% above the HPI.

19 BLAEN IFOR might now be worth an estimated £273,177.

The 307.7% inflationary increase is applied to the most recent sale price for 19 BLAEN IFOR of £67,000 on 29th April 2002. For the value to have increased from £67,000 to £273,177 over the 24 years to April 2026, the following assumptions must hold true:
