The below graph shows the average semi-detached house price in the Flintshire local authority area over time, sourced from the HPI. The four 15 Y DREFLAN sales between May 2008 and December 2022 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 November 2021 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the December 2022 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.

15 Y DREFLAN might now be worth an estimated £146,611.
This is based on house price inflation of 4.7%, between December 2022 and April 2026, for semi-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 4.7% inflationary increase is applied to the most recent sale price for 15 Y DREFLAN of £140,000 on 12th December 2022. For the value to have increased from £140,000 to £146,611 over the four years and eight months to April 2026, the following assumptions must hold true:
