FOUR OAKS 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 two FOUR OAKS sales from October 1998 and August 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 October 1998 sale was for 89% above the HPI. So the extrapolation line tracks at 89% above the HPI over time, until the August 2025 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might FOUR OAKS be worth now?

FOUR OAKS might now be worth an estimated £282,435.

This is based on house price inflation of 2.7%, between August 2025 and April 2026, 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 2.7% inflationary increase is applied to the most recent sale price for FOUR OAKS of £275,000 on 1st August 2025. For the value to have increased from £275,000 to £282,435 over the one year and four months to April 2026, the following assumptions must hold true:

• The value of FOUR OAKS has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The August 2025 sale price of £275,000 represented a fair market value for the property.
• The size, condition, and specification of FOUR OAKS has not materially changed since August 2025.
