9 CLOS GRADDFA 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 9 CLOS GRADDFA sales from May 1997 and May 2006 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 May 1997 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the May 2006 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 9 CLOS GRADDFA be worth now?

9 CLOS GRADDFA might now be worth an estimated £188,109.

This is based on house price inflation of 79.2%, between May 2006 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 79.2% inflationary increase is applied to the most recent sale price for 9 CLOS GRADDFA of £105,000 on 5th May 2006. For the value to have increased from £105,000 to £188,109 over the nineteen years and three months to February 2025, the following assumptions must hold true:

• The value of 9 CLOS GRADDFA has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
• The May 2006 sale price of £105,000 represented a fair market value for the property.
• The size, condition, and specification of 9 CLOS GRADDFA has not materially changed since May 2006.
