SIDNEY COTTAGE 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 SIDNEY COTTAGE sales between April 1999 and October 2020 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 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the October 2020 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might SIDNEY COTTAGE be worth now?

SIDNEY COTTAGE might now be worth an estimated £275,011.

This is based on house price inflation of 15.8%, between October 2020 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 15.8% inflationary increase is applied to the most recent sale price for SIDNEY COTTAGE of £237,500 on 23rd October 2020. For the value to have increased from £237,500 to £275,011 over the three years and ten months to December 2024, the following assumptions must hold true:

• The value of SIDNEY COTTAGE has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The October 2020 sale price of £237,500 represented a fair market value for the property.
• The size, condition, and specification of SIDNEY COTTAGE has not materially changed since October 2020.
