The below graph shows the average terraced house price in the Harrow local authority area over time, sourced from the HPI. The two 18 ALLINGTON ROAD sales from March 2014 and January 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 March 2014 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the January 2022 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

18 ALLINGTON ROAD might now be worth an estimated £593,680.
