MARN HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The two MARN HOUSE sales from January 1996 and January 2021 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 1996 sale was for 59% above the HPI. So the extrapolation line tracks at 59% above the HPI over time, until the January 2021 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.
