11 CASTLE SQUARE 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 four 11 CASTLE SQUARE sales between February 1996 and October 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 November 2006 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the October 2018 sale, where it falls to 37% below the HPI. The line then continues to track at 37% below the HPI.
