305 KNIGHTSFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 305 KNIGHTSFIELD sales from December 1996 and October 2004 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 1996 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the October 2004 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.
