31 TURMORE DALE 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 31 TURMORE DALE sales from May 2010 and December 2021 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 2010 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the December 2021 sale, where it falls to 20% below the HPI. The line then continues to track at 20% below the HPI.
