4 PEN DERWYDD 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 two 4 PEN DERWYDD sales from June 2002 and October 2003 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 June 2002 sale roughly matched the HPI. So the extrapolation line tracks in line HPI over time, until the October 2003 sale, which was also at roughly the same level as the HPI.

What might 4 PEN DERWYDD be worth now?

4 PEN DERWYDD might now be worth an estimated £303,317.

This is based on house price inflation of 128.1%, between October 2003 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 128.1% inflationary increase is applied to the most recent sale price for 4 PEN DERWYDD of £133,000 on 29th October 2003. For the value to have increased from £133,000 to £303,317 over the twenty years and ten months to December 2024, the following assumptions must hold true:

• The value of 4 PEN DERWYDD has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The October 2003 sale price of £133,000 represented a fair market value for the property.
