10 BLACKWELLHAMS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The four 10 BLACKWELLHAMS sales between December 2000 and November 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 July 2005 sale was for 34% below the HPI. So the extrapolation line tracks at 34% below the HPI over time, until the November 2018 sale, where it falls to 35% below the HPI. The line then continues to track at 35% below the HPI.
