TREMARIAN 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 five TREMARIAN sales between March 2002 and October 2022 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 February 2013 sale was for 66% above the HPI. So the extrapolation line tracks at 66% above the HPI over time, until the October 2022 sale, where it falls to 23% above the HPI. The line then continues to track at 23% above the HPI.

What might TREMARIAN be worth now?

TREMARIAN might now be worth an estimated £386,590.

This is based on house price deflation of 0.9%, between October 2022 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 0.9% deflationary decrease is applied to the most recent sale price for TREMARIAN of £390,000 on 7th October 2022. For the value to have decreased from £390,000 to £386,590 over the three years and eight months to February 2025, the following assumptions must hold true:

• The value of TREMARIAN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The October 2022 sale price of £390,000 represented a fair market value for the property.
• The size, condition, and specification of TREMARIAN has not materially changed since October 2022.
