11 CAE Y DDERWEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Flintshire local authority area over time, sourced from the HPI. The two 11 CAE Y DDERWEN sales from March 2002 and May 2009 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 March 2002 sale was for 69% below the HPI. So the extrapolation line tracks at 69% below the HPI over time, until the May 2009 sale, where it rises to 66% below the HPI. The line then continues to track at 66% below the HPI.

What might 11 CAE Y DDERWEN be worth now?

This is based on house price inflation of 61.4%, between May 2009 and December 2024, for detached houses, in the Flintshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 61.4% inflationary increase is applied to the most recent sale price for 11 CAE Y DDERWEN of £66,000 on 8th May 2009. For the value to have increased from £66,000 to £106,543 over the fourteen years and five months to December 2024, the following assumptions must hold true:
