21 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 two 21 THIRLMERE sales from May 1999 and December 2006 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 1999 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the December 2006 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.
