PENLON 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 PENLON sales between January 2003 and September 2013 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 October 2009 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the September 2013 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might PENLON be worth now?

PENLON might now be worth an estimated £348,696.

This is based on house price inflation of 70.5%, between September 2013 and June 2025, 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 70.5% inflationary increase is applied to the most recent sale price for PENLON of £204,500 on 24th September 2013. For the value to have increased from £204,500 to £348,696 over the twelve years and three months to June 2025, the following assumptions must hold true:

• The value of PENLON has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The September 2013 sale price of £204,500 represented a fair market value for the property.
• The size, condition, and specification of PENLON has not materially changed since September 2013.
