21 UPPER GROVE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hampshire local authority area over time, sourced from the HPI. The two 21 UPPER GROVE ROAD sales from January 2002 and October 2010 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 2002 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the October 2010 sale, where it rises to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 21 UPPER GROVE ROAD be worth now?

This is based on house price inflation of 68.4%, between October 2010 and August 2025, for detached houses, in the East Hampshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
