35 LANSDOWNE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Slough local authority area over time, sourced from the HPI. The three 35 LANSDOWNE AVENUE sales between September 1996 and September 2004 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 April 1998 sale was for 98% above the HPI. So the extrapolation line tracks at 98% above the HPI over time, until the September 2004 sale, where it falls to 64% above the HPI. The line then continues to track at 64% above the HPI.
