The below table shows the price paid for the two sales, along with the average detached price in the Flintshire local authority area for the corresponding sale date.

The below graph shows the average detached house price in the Flintshire local authority area over time, sourced from the HPI. The two PEN LLAN sales from September 2017 and April 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 September 2017 sale was for 77% above the HPI. So the extrapolation line tracks at 77% above the HPI over time, until the April 2021 sale, where it rises to 135% above the HPI. The line then continues to track at 135% above the HPI.
PEN LLAN might now be worth an estimated £727,882.
This is based on house price inflation of 21.3%, between April 2021 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 21.3% inflationary increase is applied to the most recent sale price for PEN LLAN of £600,000 on 28th April 2021. For the value to have increased from £600,000 to £727,882 over the two years and four months to December 2024, the following assumptions must hold true:
