21 CASTELL Y FAN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 21 CASTELL Y FAN sales from December 2001 and July 2005 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 2001 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the July 2005 sale, where it falls to 46% above the HPI. The line then continues to track at 46% above the HPI.

What might 21 CASTELL Y FAN be worth now?

This is based on house price inflation of 91.9%, between July 2005 and February 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 91.9% inflationary increase is applied to the most recent sale price for 21 CASTELL Y FAN of £150,000 on 29th July 2005. For the value to have increased from £150,000 to £287,869 over the twenty years and five months to February 2025, the following assumptions must hold true:
