18 ROCKSIDE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Gloucestershire local authority area over time, sourced from the HPI. The three 18 ROCKSIDE AVENUE sales between April 2007 and August 2016 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 2012 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the August 2016 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 18 ROCKSIDE AVENUE be worth now?
