21 CLOS COED DUON 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 21 CLOS COED DUON sales between February 1996 and July 2017 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 October 1999 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the July 2017 sale, where it rises to 35% above the HPI. The line then continues to track at 35% above the HPI.

What might 21 CLOS COED DUON be worth now?

21 CLOS COED DUON might now be worth an estimated £265,793.

This is based on house price inflation of 60.6%, between July 2017 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 60.6% inflationary increase is applied to the most recent sale price for 21 CLOS COED DUON of £165,500 on 21st July 2017. For the value to have increased from £165,500 to £265,793 over the six years and seven months to December 2024, the following assumptions must hold true:
