75 UPPER KING STREET 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 seven 75 UPPER KING STREET sales between December 1997 and December 2022 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 September 2017 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the December 2022 sale, where it rises to 27% below the HPI. The line then continues to track at 27% below the HPI.
