20 STONE STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cambridge local authority area over time, sourced from the HPI. The four 20 STONE STREET sales between October 1998 and September 2016 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 December 2006 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the September 2016 sale, where it falls to 54% below the HPI. The line then continues to track at 54% below the HPI.

What might 20 STONE STREET be worth now?
