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 2008 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 September 2007 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the September 2008 sale, where it rises to 144% above the HPI. The line then continues to track at 144% above the HPI.

What might PENLON be worth now?

PENLON might now be worth an estimated £776,316.

This is based on house price inflation of 55.3%, between September 2008 and July 2026, 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 55.3% inflationary increase is applied to the most recent sale price for PENLON of £500,000 on 1st September 2008. For the value to have increased from £500,000 to £776,316 over the eighteen years and two months to July 2026, 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 2008 sale price of £500,000 represented a fair market value for the property.
  • The size, condition, and specification of PENLON has not materially changed since September 2008.
