11 LON ISAF Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The three 11 LON ISAF sales between January 2000 and July 2021 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 July 2011 sale was for 51% above the HPI. So the extrapolation line tracks at 51% above the HPI over time, until the July 2021 sale, where it rises to 54% above the HPI. The line then continues to track at 54% above the HPI.

What might 11 LON ISAF be worth now?

11 LON ISAF might now be worth an estimated £302,763.

This is based on house price inflation of 10.1%, between July 2021 and December 2024, for semi-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 10.1% inflationary increase is applied to the most recent sale price for 11 LON ISAF of £275,000 on 28th July 2021. For the value to have increased from £275,000 to £302,763 over the two years and seven months to December 2024, the following assumptions must hold true:

• The value of 11 LON ISAF has moved in line with the HPI for semi-detached houses in the Isle of Anglesey local authority area.
• The July 2021 sale price of £275,000 represented a fair market value for the property.
