21 DEYNCOURT GARDENS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Havering local authority area over time, sourced from the HPI. The two 21 DEYNCOURT GARDENS sales from February 2001 and December 2006 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 February 2001 sale was for 147% above the HPI. So the extrapolation line tracks at 147% above the HPI over time, until the December 2006 sale, where it falls to 98% above the HPI. The line then continues to track at 98% above the HPI.
