35 BLACKWATER WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The three 35 BLACKWATER WAY sales between June 1998 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 July 2002 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the September 2004 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.
