20 Y BERTHLOG Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Flintshire local authority area over time, sourced from the HPI. The three 20 Y BERTHLOG sales between November 2001 and February 2025 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 January 2018 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the February 2025 sale, where it rises to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 20 Y BERTHLOG be worth now?

This is based on house price inflation of 2%, between February 2025 and June 2025, 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 2% inflationary increase is applied to the most recent sale price for 20 Y BERTHLOG of £175,000 on 28th February 2025. For the value to have increased from £175,000 to £178,585 over the eight months to June 2025, the following assumptions must hold true:

• The value of 20 Y BERTHLOG has moved in line with the HPI for semi-detached houses in the Flintshire local authority area.
