7 GERLLAN 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 two 7 GERLLAN sales from February 2007 and March 2017 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 February 2007 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the March 2017 sale, where it rises to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 7 GERLLAN be worth now?

7 GERLLAN might now be worth an estimated £322,506.

This is based on house price inflation of 39.6%, between March 2017 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 39.6% inflationary increase is applied to the most recent sale price for 7 GERLLAN of £231,000 on 6th March 2017. For the value to have increased from £231,000 to £322,506 over the eight years and one month to February 2025, the following assumptions must hold true:

• The value of 7 GERLLAN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The March 2017 sale price of £231,000 represented a fair market value for the property.
• The size, condition, and specification of 7 GERLLAN has not materially changed since March 2017.
