20 PORTMAN CLOSE 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 20 PORTMAN CLOSE sales between June 1996 and January 2018 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 June 2012 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the January 2018 sale, where it falls to 41% below the HPI. The line then continues to track at 41% below the HPI.
