THELDEN 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 three THELDEN sales between November 2003 and October 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 February 2019 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the October 2021 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might THELDEN be worth now?

THELDEN might now be worth an estimated £330,650.

This is based on house price inflation of 14%, between October 2021 and February 2025, 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 14% inflationary increase is applied to the most recent sale price for THELDEN of £290,000 on 7th October 2021. For the value to have increased from £290,000 to £330,650 over the four years and eight months to February 2025, the following assumptions must hold true:

• The value of THELDEN has moved in line with the HPI for detached houses in the Flintshire local authority area.
• The October 2021 sale price of £290,000 represented a fair market value for the property.
• The size, condition, and specification of THELDEN has not materially changed since October 2021.
