CAER FFYNNON 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 three CAER FFYNNON sales between December 2006 and October 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 May 2016 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the October 2021 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might CAER FFYNNON be worth now?

CAER FFYNNON might now be worth an estimated £254,391.

This is based on house price inflation of 9.4%, between October 2021 and June 2025, 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 9.4% inflationary increase is applied to the most recent sale price for CAER FFYNNON of £232,500 on 29th October 2021. For the value to have increased from £232,500 to £254,391 over the four years and four months to June 2025, the following assumptions must hold true:

• The value of CAER FFYNNON has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The October 2021 sale price of £232,500 represented a fair market value for the property.
• The size, condition, and specification of CAER FFYNNON has not materially changed since October 2021.
