4 ALLONBY DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 4 ALLONBY DRIVE sales from April 1995 and December 2020 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 1995 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the December 2020 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 4 ALLONBY DRIVE be worth now?
