11 PEN GERDDI Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The four 11 PEN GERDDI sales between April 1995 and October 2023 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 August 2006 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the October 2023 sale, where it falls to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 11 PEN GERDDI be worth now?

11 PEN GERDDI might now be worth an estimated £208,442.

This is based on house price deflation of 8.6%, between October 2023 and December 2024, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 8.6% deflationary decrease is applied to the most recent sale price for 11 PEN GERDDI of £228,000 on 20th October 2023. For the value to have decreased from £228,000 to £208,442 over the ten months to December 2024, the following assumptions must hold true:

• The value of 11 PEN GERDDI has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The October 2023 sale price of £228,000 represented a fair market value for the property.
• The size, condition, and specification of 11 PEN GERDDI has not materially changed since October 2023.
