20 CAE GWYN 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 20 CAE GWYN sales between February 2004 and October 2018 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 August 2014 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the October 2018 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

What might 20 CAE GWYN be worth now?

20 CAE GWYN might now be worth an estimated £437,322.

This is based on house price inflation of 31.1%, between October 2018 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 31.1% inflationary increase is applied to the most recent sale price for 20 CAE GWYN of £333,500 on 26th October 2018. For the value to have increased from £333,500 to £437,322 over the seven years and four months to June 2025, the following assumptions must hold true:

• The value of 20 CAE GWYN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The October 2018 sale price of £333,500 represented a fair market value for the property.
• The size, condition, and specification of 20 CAE GWYN has not materially changed since October 2018.
