39 PROSPECT LANE 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 39 PROSPECT LANE sales between September 1996 and April 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 2002 sale was for 163% above the HPI. So the extrapolation line tracks at 163% above the HPI over time, until the April 2018 sale, where it falls to 125% above the HPI. The line then continues to track at 125% above the HPI.
