11 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 four 11 CLOS GRADDFA sales between May 1997 and November 2010 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 2007 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the November 2010 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 11 CLOS GRADDFA be worth now?

11 CLOS GRADDFA might now be worth an estimated £212,363.

This is based on house price inflation of 94.8%, between November 2010 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 94.8% inflationary increase is applied to the most recent sale price for 11 CLOS GRADDFA of £109,000 on 26th November 2010. For the value to have increased from £109,000 to £212,363 over the fifteen years and nine months to February 2025, the following assumptions must hold true:

• The value of 11 CLOS GRADDFA has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
• The November 2010 sale price of £109,000 represented a fair market value for the property.
• The size, condition, and specification of 11 CLOS GRADDFA has not materially changed since November 2010.
