26 TREFONWYS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The four 26 TREFONWYS sales between November 1998 and February 2021 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 January 2004 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the February 2021 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 26 TREFONWYS be worth now?

26 TREFONWYS might now be worth an estimated £318,315.

This is based on house price inflation of 14.5%, between February 2021 and December 2024, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 14.5% inflationary increase is applied to the most recent sale price for 26 TREFONWYS of £278,000 on 3rd February 2021. For the value to have increased from £278,000 to £318,315 over the two years and two months to December 2024, the following assumptions must hold true:

• The value of 26 TREFONWYS has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The February 2021 sale price of £278,000 represented a fair market value for the property.
• The size, condition, and specification of 26 TREFONWYS has not materially changed since February 2021.
