12 GASSIOT WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Sutton local authority area over time, sourced from the HPI. The three 12 GASSIOT WAY sales between October 2002 and December 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 January 2004 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the December 2020 sale, where it falls to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 12 GASSIOT WAY be worth now?

This is based on house price inflation of 13.3%, between December 2020 and February 2025, for semi-detached houses, in the Sutton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 13.3% inflationary increase is applied to the most recent sale price for 12 GASSIOT WAY of £500,000 on 17th December 2020. For the value to have increased from £500,000 to £566,516 over the five years and ten months to February 2025, the following assumptions must hold true:
