12 WILTON GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Kingston upon Thames local authority area over time, sourced from the HPI. The three 12 WILTON GROVE sales between January 2004 and June 2023 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 March 2007 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the June 2023 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 12 WILTON GROVE be worth now?

This is based on house price deflation of 5.4%, between June 2023 and December 2024, for detached houses, in the Kingston upon Thames local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
