GWYLANNEDD 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 GWYLANNEDD sales between June 1998 and January 2025 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 December 2020 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the January 2025 sale, where it rises to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might GWYLANNEDD be worth now?

GWYLANNEDD might now be worth an estimated £228,205.

This is based on house price inflation of 3.7%, between January 2025 and June 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 3.7% inflationary increase is applied to the most recent sale price for GWYLANNEDD of £220,000 on 15th January 2025. For the value to have increased from £220,000 to £228,205 over the seven months to June 2025, the following assumptions must hold true:

• The value of GWYLANNEDD has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The January 2025 sale price of £220,000 represented a fair market value for the property.
• The size, condition, and specification of GWYLANNEDD has not materially changed since January 2025.
