18 DAN YR ARDD 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 three 18 DAN YR ARDD sales between August 1997 and December 2003 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 July 2001 sale was for 64% above the HPI. So the extrapolation line tracks at 64% above the HPI over time, until the December 2003 sale, where it rises to 66% above the HPI. The line then continues to track at 66% above the HPI.

What might 18 DAN YR ARDD be worth now?

This is based on house price inflation of 155.2%, between December 2003 and December 2024, 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 155.2% inflationary increase is applied to the most recent sale price for 18 DAN YR ARDD of £127,950 on 12th December 2003. For the value to have increased from £127,950 to £326,476 over the 21 years to December 2024, the following assumptions must hold true:
