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 TAN Y MARIAN sales from July 2015 and October 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 2015 sale was for 70% below the HPI. So the extrapolation line tracks at 70% below the HPI over time, until the October 2021 sale, where it rises to 51% below the HPI. The line then continues to track at 51% below the HPI.
TAN Y MARIAN might now be worth an estimated £153,909.
This is based on house price inflation of 5.4%, between October 2021 and February 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 5.4% inflationary increase is applied to the most recent sale price for TAN Y MARIAN of £146,000 on 7th October 2021. For the value to have increased from £146,000 to £153,909 over the four years and eight months to February 2025, the following assumptions must hold true:
