12 ALLINGHAM STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Islington local authority area over time, sourced from the HPI. The four 12 ALLINGHAM STREET sales between November 1996 and July 2022 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 April 2013 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the July 2022 sale, where it rises to 20% above the HPI. The line then continues to track at 20% above the HPI.
