BRONDDERWEN 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 BRONDDERWEN sales between June 2007 and June 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 January 2013 sale was for 69% below the HPI. So the extrapolation line tracks at 69% below the HPI over time, until the June 2021 sale, where it rises to 45% below the HPI. The line then continues to track at 45% below the HPI.

What might BRONDDERWEN be worth now?

BRONDDERWEN might now be worth an estimated £165,655.

This is based on house price inflation of 10.4%, between June 2021 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 10.4% inflationary increase is applied to the most recent sale price for BRONDDERWEN of £150,000 on 14th June 2021. For the value to have increased from £150,000 to £165,655 over the four years and four months to February 2025, the following assumptions must hold true:

• The value of BRONDDERWEN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The June 2021 sale price of £150,000 represented a fair market value for the property.
• The size, condition, and specification of BRONDDERWEN has not materially changed since June 2021.
