12 CLOS GRADDFA Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three 12 CLOS GRADDFA sales between May 1997 and June 2021 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 2016 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the June 2021 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 12 CLOS GRADDFA be worth now?

12 CLOS GRADDFA might now be worth an estimated £336,663.

This is based on house price inflation of 24.7%, between June 2021 and December 2024, for 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 24.7% inflationary increase is applied to the most recent sale price for 12 CLOS GRADDFA of £270,000 on 18th June 2021. For the value to have increased from £270,000 to £336,663 over the two years and six months to December 2024, the following assumptions must hold true:

• The value of 12 CLOS GRADDFA has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The June 2021 sale price of £270,000 represented a fair market value for the property.
