21 LYTTON FIELDS 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 three 21 LYTTON FIELDS sales between June 2002 and September 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 2005 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the September 2021 sale, where it rises to 25% above the HPI. The line then continues to track at 25% above the HPI.
