FRONWEN 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 two FRONWEN sales from October 2016 and March 2024 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 October 2016 sale was for 30% above the HPI. So the extrapolation line tracks at 30% above the HPI over time, until the March 2024 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might FRONWEN be worth now?

FRONWEN might now be worth an estimated £370,191.

This is based on house price inflation of 3.5%, between March 2024 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 3.5% inflationary increase is applied to the most recent sale price for FRONWEN of £357,500 on 8th March 2024. For the value to have increased from £357,500 to £370,191 over the nine months to June 2025, the following assumptions must hold true:

• The value of FRONWEN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The March 2024 sale price of £357,500 represented a fair market value for the property.
• The size, condition, and specification of FRONWEN has not materially changed since March 2024.
