21 LON ISAF 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 21 LON ISAF sales between August 1996 and May 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 1997 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the May 2019 sale, where it falls to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 21 LON ISAF be worth now?

21 LON ISAF might now be worth an estimated £237,211.

This is based on house price inflation of 32.2%, between May 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 32.2% inflationary increase is applied to the most recent sale price for 21 LON ISAF of £179,500 on 31st May 2019. For the value to have increased from £179,500 to £237,211 over the four years and five months to December 2024, the following assumptions must hold true:

• The value of 21 LON ISAF has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The May 2019 sale price of £179,500 represented a fair market value for the property.
