12 TYDDYN 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 two 12 TYDDYN ISAF sales from August 2007 and February 2018 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 2007 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the February 2018 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 12 TYDDYN ISAF be worth now?

12 TYDDYN ISAF might now be worth an estimated £280,508.

This is based on house price inflation of 43.9%, between February 2018 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 43.9% inflationary increase is applied to the most recent sale price for 12 TYDDYN ISAF of £195,000 on 23rd February 2018. For the value to have increased from £195,000 to £280,508 over the seven years to February 2025, the following assumptions must hold true:
