TYN Y BERTH 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 TYN Y BERTH sales from July 2011 and November 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 July 2011 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the November 2021 sale, where it rises to 27% below the HPI. The line then continues to track at 27% below the HPI.

What might TYN Y BERTH be worth now?

TYN Y BERTH might now be worth an estimated £227,823.

This is based on house price inflation of 13.3%, between November 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 13.3% inflationary increase is applied to the most recent sale price for TYN Y BERTH of £201,000 on 8th November 2021. For the value to have increased from £201,000 to £227,823 over the two years and eleven months to December 2024, the following assumptions must hold true:

• The value of TYN Y BERTH has moved in line with the HPI for detached houses in the Flintshire local authority area.
• The November 2021 sale price of £201,000 represented a fair market value for the property.
