48 CASTLE STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dartford local authority area over time, sourced from the HPI. The two 48 CASTLE STREET sales from July 2014 and October 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 July 2014 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the October 2016 sale, where it falls to 51% below the HPI. The line then continues to track at 51% below the HPI.

What might 48 CASTLE STREET be worth now?
