23 GRASMERE AVENUE 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 23 GRASMERE AVENUE sales from November 2009 and July 2017 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 November 2009 sale was for 70% below the HPI. So the extrapolation line tracks at 70% below the HPI over time, until the July 2017 sale, where it rises to 60% below the HPI. The line then continues to track at 60% below the HPI.

What might 23 GRASMERE AVENUE be worth now?

This is based on house price inflation of 13.5%, between July 2017 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 13.5% inflationary increase is applied to the most recent sale price for 23 GRASMERE AVENUE of £740,000 on 26th July 2017. For the value to have increased from £740,000 to £839,925 over the six years and seven months to December 2024, the following assumptions must hold true:
