20C WEST SIDE COMMON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Merton local authority area over time, sourced from the HPI. The two 20C WEST SIDE COMMON sales from February 2006 and April 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 2006 sale was for 237% above the HPI. So the extrapolation line tracks at 237% above the HPI over time, until the April 2020 sale, where it falls to 107% above the HPI. The line then continues to track at 107% above the HPI.

What might 20C WEST SIDE COMMON be worth now?

20C WEST SIDE COMMON might now be worth an estimated £4,341,059.

This is based on house price inflation of 7.9%, between April 2020 and December 2024, for detached houses, in the Merton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 7.9% inflationary increase is applied to the most recent sale price for 20C WEST SIDE COMMON of £4,025,000 on 17th April 2020. For the value to have increased from £4,025,000 to £4,341,059 over the three years and four months to December 2024, the following assumptions must hold true:

• The value of 20C WEST SIDE COMMON has moved in line with the HPI for detached houses in the Merton local authority area.
• The April 2020 sale price of £4,025,000 represented a fair market value for the property.
