20 MANDEVILLE RISE 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 20 MANDEVILLE RISE sales from August 2011 and December 2019 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 August 2011 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the December 2019 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.
