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 two 15 TYDDYN ISAF sales from April 2016 and August 2023 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 April 2016 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the August 2023 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.
15 TYDDYN ISAF might now be worth an estimated £214,833.
This is based on house price deflation of 0.1%, between August 2023 and February 2025, 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 0.1% deflationary decrease is applied to the most recent sale price for 15 TYDDYN ISAF of £215,000 on 25th August 2023. For the value to have decreased from £215,000 to £214,833 over the two years and six months to February 2025, the following assumptions must hold true:
