18 SYLVANDALE 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 three 18 SYLVANDALE sales between March 2008 and August 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 February 2014 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the August 2019 sale, where it rises to 31% below the HPI. The line then continues to track at 31% below the HPI.
