17 INGRAM AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The three 17 INGRAM AVENUE sales between March 1998 and September 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 November 2011 sale was for 1569% above the HPI. So the extrapolation line tracks at 1569% above the HPI over time, until the September 2023 sale, where it falls to 576% above the HPI. The line then continues to track at 576% above the HPI.
