387 COMMONSIDE EAST Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Merton local authority area over time, sourced from the HPI. The two 387 COMMONSIDE EAST sales from September 2014 and January 2018 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 September 2014 sale was for 55% below the HPI. So the extrapolation line tracks at 55% below the HPI over time, until the January 2018 sale, where it rises to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 387 COMMONSIDE EAST be worth now?

This is based on house price inflation of 19.4%, between January 2018 and February 2025, for semi-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 19.4% inflationary increase is applied to the most recent sale price for 387 COMMONSIDE EAST of £450,000 on 31st January 2018. For the value to have increased from £450,000 to £537,301 over the six years and eleven months to February 2025, the following assumptions must hold true:
