21 BLAKES WAY 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 four 21 BLAKES WAY sales between August 1997 and November 2017 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 May 2005 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the November 2017 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.
