Y GARREG 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 Y GARREG sales between July 2013 and April 2019 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 2015 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the April 2019 sale, where it rises to 102% above the HPI. The line then continues to track at 102% above the HPI.

What might Y GARREG be worth now?

Y GARREG might now be worth an estimated £597,391.

This is based on house price inflation of 25.8%, between April 2019 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 25.8% inflationary increase is applied to the most recent sale price for Y GARREG of £475,000 on 4th April 2019. For the value to have increased from £475,000 to £597,391 over the four years and four months to December 2024, the following assumptions must hold true:

• The value of Y GARREG has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The April 2019 sale price of £475,000 represented a fair market value for the property.
• The size, condition, and specification of Y GARREG has not materially changed since April 2019.
