GWYNANT 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 GWYNANT sales from September 2010 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 September 2010 sale was for 73% below the HPI. So the extrapolation line tracks at 73% below the HPI over time, until the October 2022 sale, where it rises to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might GWYNANT be worth now?

GWYNANT might now be worth an estimated £199,851.

This is based on house price deflation of 4.8%, between October 2022 and December 2024, 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 4.8% deflationary decrease is applied to the most recent sale price for GWYNANT of £210,000 on 28th October 2022. For the value to have decreased from £210,000 to £199,851 over the one year and ten months to December 2024, the following assumptions must hold true:

• The value of GWYNANT has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The October 2022 sale price of £210,000 represented a fair market value for the property.
• The size, condition, and specification of GWYNANT has not materially changed since October 2022.
