1 MARK LANE 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 1 MARK LANE sales from July 2000 and December 2024 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 July 2000 sale was for 80% below the HPI. So the extrapolation line tracks at 80% below the HPI over time, until the December 2024 sale, where it rises to 60% below the HPI. The line then continues to track at 60% below the HPI.

What might 1 MARK LANE be worth now?

1 MARK LANE might now be worth an estimated £123,008.

This is based on house price inflation of 1.7%, between December 2024 and April 2026, 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 1.7% inflationary increase is applied to the most recent sale price for 1 MARK LANE of £121,000 on 16th December 2024. For the value to have increased from £121,000 to £123,008 over the two years and eight months to April 2026, the following assumptions must hold true:

• The value of 1 MARK LANE has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The December 2024 sale price of £121,000 represented a fair market value for the property.
• The size, condition, and specification of 1 MARK LANE has not materially changed since December 2024.
