3 ROUNDWOOD PARK Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The three 3 ROUNDWOOD PARK sales between December 1997 and December 2015 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 October 2007 sale was for 132% above the HPI. So the extrapolation line tracks at 132% above the HPI over time, until the December 2015 sale, where it falls to 113% above the HPI. The line then continues to track at 113% above the HPI.
