12 TROWLOCK AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The three 12 TROWLOCK AVENUE sales between February 1995 and February 2019 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 2002 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the February 2019 sale, where it rises to 42% above the HPI. The line then continues to track at 42% above the HPI.
