ARWYN 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 ARWYN sales between May 2002 and August 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 April 2003 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the August 2018 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might ARWYN be worth now?

ARWYN might now be worth an estimated £267,181.

This is based on house price inflation of 33.6%, between August 2018 and February 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 33.6% inflationary increase is applied to the most recent sale price for ARWYN of £200,000 on 23rd August 2018. For the value to have increased from £200,000 to £267,181 over the seven years and six months to February 2025, the following assumptions must hold true:

• The value of ARWYN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The August 2018 sale price of £200,000 represented a fair market value for the property.
• The size, condition, and specification of ARWYN has not materially changed since August 2018.
