1 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 three 1 PEN GERDDI sales between July 1995 and December 2019 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 2012 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the December 2019 sale, where it rises to 28% below the HPI. The line then continues to track at 28% below the HPI.

What might 1 PEN GERDDI be worth now?

1 PEN GERDDI might now be worth an estimated £218,530.

This is based on house price inflation of 21.4%, between December 2019 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 21.4% inflationary increase is applied to the most recent sale price for 1 PEN GERDDI of £180,000 on 3rd December 2019. For the value to have increased from £180,000 to £218,530 over the five years to December 2024, the following assumptions must hold true:

• The value of 1 PEN GERDDI has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The December 2019 sale price of £180,000 represented a fair market value for the property.
• The size, condition, and specification of 1 PEN GERDDI has not materially changed since December 2019.
