33 THIRLMERE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The four 33 THIRLMERE sales between June 1999 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 March 2012 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the August 2019 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.
