BRYN DERWEN 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 BRYN DERWEN sales between February 1999 and July 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 March 2008 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the July 2021 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might BRYN DERWEN be worth now?

BRYN DERWEN might now be worth an estimated £294,508.

This is based on house price inflation of 13.7%, between July 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 13.7% inflationary increase is applied to the most recent sale price for BRYN DERWEN of £259,000 on 2nd July 2021. For the value to have increased from £259,000 to £294,508 over the four years and one month to June 2025, the following assumptions must hold true:

• The value of BRYN DERWEN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The July 2021 sale price of £259,000 represented a fair market value for the property.
• The size, condition, and specification of BRYN DERWEN has not materially changed since July 2021.
